Our chemists and engineers perform chemical analysis on aluminum base alloys to identify or determine adherence and certify to ASTM and other industry specifications.

Types of Aluminum Alloys We Analyze
1000 series are essentially pure aluminum with a minimum 99% aluminum content by weight and can be work hardened.
2000 series are alloyed with copper, can be precipitation hardened to strengths comparable to steel. Formerly referred to as duralumin, they were once the most common aerospace alloys but were susceptible to stress corrosion cracking and are increasingly replaced by 7000 series in new designs.
3000 series are alloyed with manganese and can be work hardened.
4000 series are alloyed with silicon. Variations of Aluminum-silicon alloys intended for casting (and therefore not included in 4000 series) are also known as silumin.
5000 series are alloyed with magnesium, and offer superb corrosion resistance, making them suitable for marine applications. Also, 5083 alloy has the highest strength of not heat-treated alloys.
6000 series are alloyed with magnesium and silicon. They are easy to machine, are weldable, and can be precipitation hardened, but not to the high strengths that 2000 and 7000 can reach. 6061 alloy is one of the most commonly used general-purpose aluminum alloys.
7000 series are alloyed with zinc and can be precipitation hardened to the highest strengths of any(ultimate tensile strength up to 700 MPa for the 7068 alloys).
8000 series are alloyed with other elements which are not covered by other series.
