There are many different grades of aluminium available. Aluminum is almost always alloyed, which markedly improves its mechanical properties. The International Alloy Designation System is the most widely accepted naming scheme for alloys. Below we break down each series of aluminium alloy.

1000 Series

1000 Series aluminium are essentially pure aluminium with a minimum 99% aluminium. The 1000 Series is considered commercially pure aluminium and is soft and very ductile. These alloys are selected primarily for their superior corrosion resistance. A few examples would be use in specialized chemical tanks and piping, or for their excellent electrical conductivity as in bus bar applications. Due to their relatively poor mechanical properties they would seldom be used for general structural applications.


2000 Series

2000 Series aluminium are aluminium that are alloyed with copper ranging from 0.7% to 6.8% copper content. The 2000 series is widely used in the aircraft and aerospace industry due to it’s high strength to weight ratio. It also has excellent fatigue properties when compared with other aluminium alloys. The 2000 series does however does have it’s limitations, most notably in weld-ability where it can be susceptible to hot-cracking and stress corrosion cracking without proper welding procedure. 2000 series aluminium does also have a poor resistance to corrosion without the addition of a finishing layer such as chem film or anodizing. Common uses for 2000 series, other than the aircraft industry, include aluminium rivets, fasteners and screw machine parts.

2014 and 2024 are among the most comon 2000 series of aluminium alloys, and are available at PartsBadger

3000 Series

3000 Series aluminium are aluminium alloyed with manganese, with manganese composing 0.05% to 1.8% content.  3000 series aluminium has moderate strength (about 20% stronger than 1000 Series), good corrosion resistance and good form-ability. 3000 series performs well at elevated temperatures and was originally used in household pots and pans. Today they are a major component in heat exchangers. The moderate strength however normally precludes their use in structural applications.

4000 Series

4000 Series aluminium is a aluminium alloyed with silicon, with the silicon content being 0.6% to 21.5%. 4000 series aluminium is desirable for filler material used for both fusion welding and brazing. The reduced melting point and fluidity when molten create these desirable characteristics.

5000 Series

5000 Series aluminium is alloyed with magnesium, with a magnesium content of 0.2% to 6.2%. The 5000 series aluminium is the strongest non-heat treatable alloy. This along with great weld-ability, good corrosion resistance and good fatigue properties in high temper conditions make the 5000 series very versatile. There are a number of applications for 5000 series aluminium including home, marine, transportation, including ground and aircraft.

5080 and 5083 aluminium are the 5000 series aluminum alloys that are offered at PartsBadger.

6000 Series

6000 Series aluminium is a aluminium that is alloyed with both magnesium and silicon. 6000 Series aluminium offers good mechanical fatigue properties and excellent corrosion resistance. Technically not as strong as a 2000 or 7000 series alloys, the 6000 series is among the most common used general purpose alloys. The 6000 series takes very well to machining, welding and can be precipitation hardened. The 6000 series has a far ranging application ability which is aided by it’s excellent finishing characteristics and the best alloy for anodizing applications.

6061, 6063 and 6082 aluminium are the 6000 series aluminium’s available at PartsBadger.

7000 Series

7000 Series aluminium are aluminium’s that are alloyed with zinc, with a zinc content of 0.8% to 12%. The 7000 series is considered among the strongest aluminium alloy’s and is mainly used in “high performance” applications. The 7000 series displays excellent fatigue properties, however it does have drawbacks. 7000 series aluminium has a poor corrosion resistance unless chem treated, anodized, primed or painted. It also has a limited weld-ability, taking to spot welds, however not fusion welding. In sheet form it can act as a good cladding alloy.

7075 aluminium is available at PartsBadger.


Magnesium is a lightweight metal, two-thirds the density of aluminium. Although a alkaline metal, due to a oxide layer which in fairly impermeable it does not require a oxygen free environment. Historically used in aircraft and automotive sectors for it’s light weight properties. In more recent history with the rise of mobile electronics magnesium, due to it’s good mechanical and electrical properties, has become a key component.

Magnesium is in stock and available here at PartsBadger.


Brass is a metal alloy made of copper and zinc. Brass generally exhibits a higher malleability and have a high corrosion resistance. Historical uses for brass have been wide and varied over the years. Most of the common uses revolve around decoration for it’s bright gold-like appearance. Commercially brass is also widely used in low friction applications such as bearings, locks, gears, plumbing and electrical applications. Brass also offers a germicidal property due to it’s copper content. Overall brass still has a wide span of uses from mechanical and industrial to artwork and decorations.

Red Copper

Copper is the first metal manipulated by man and to this day remains a very important metal in a variety of industries. Most of the modern uses for copper revolve around electronics, wiring and the telecommunications industry due to it’s conductivity. Copper also offers antimicrobial properties that can kill bacteria, viruses and yeast on contact. This property has been expanding the uses of copper in both the medical fields and in various textile and garment industries. Copper has fair corrosion resistance properties, but will experience galvanic corrosion when placed against other metals. Copper also oxidizes when exposed to air and water. Most of us have seen this oxidization on older copper, which turns the surface from a red color to a green hue.

Bronze is a alloy normally consisting of 88% copper and 12% tin. Various alloy’s of bronze are used in many different industries. Most are very ductile, softer and weaker than most steels. Bronze does conduct heat and electricity better than most steels, and is corrosion resistant. Electrical contacts, bearing, sculptures, instruments and of course bronze medals are just a few examples of uses.

Stainless Steel

Stainless steel is a steel alloy with a minimum of 10.5% chromium content. Stainless steel is used where the strength of steel and high corrosion resistance is needed. Stainless steel is used over so many varying fields from architecture and industrial equipment to jewelry, household hardware and surgical equipment. The corrosion resistance makes stainless steel a commonly relied on choice for quality control pieces, that can be referred back to time and time again.

M303 Stainless steel

M303 is a alloy of stainless steel which was developed specifically to improve machine-ability, yet maintain good mechanical and corrosion resistance properties. Heavily machined parts like gears, screws, nuts and bolts are a few areas where M303 shows a slight superiority to normal stainless steel. The M303 alloy does have a slightly reduced corrosion resistance, which is more apparent in moist or marine enviroments.

A3 Steel

A3 steel is a carbon steel that is air hardened, and is normally a tool steel. The A3 designation refers to the composition of the steel which is 1.25% carbon, 0.5% manganese, 5.0% chromium, 0.3% nickel, 0.9%-1.4% molybdenum and 0.8%-1.4% vanadium. This composition makes the A3 alloy have good wear and corrosion resistance. This particular alloy can commonly be found in hand tools as well as industrialy uses such as railroad tracks.

1045 (#45) Steel

#45 Steel is a medium carbon content steel. This steel has excellent machineability, and durability when used in a structure. One of the benefits is the weld-ability, lending itself to being used in industrial and non-industrial fields. Being a medium carbon steel the corrosion resistance is lower than other alloyed steel’s.
