1050A Commercial Aluminium Alloy1050A (S1B) Aluminium Alloy

Aluminium Alloy Sheet

An unalloyed (‘pure’) non-heat treatable rolled aluminium sheet engineered for general sheet metal work where high mechanical properties are not required.

Internationally recognised grade EN AW 1050A H14 – 99.50% pure aluminium (Al 99.5) sheet strain hardened to the half-hard temper. The previous BS specification was known as S1B and the half-hard temper was known as H4, giving S1B H4. Smiths range of 1050A will meet all appropriate national/international standards.


Pure aluminium has only fair machinability due to the softness of the alloy. The half-hard temper increases the hardness over the annealed/soft base alloy but could not be described as free chipping compared to the harder, alloyed aluminium’s.

We recommend aluminium geometry cutting tools running at a reasonable speed to avoid the edge build-up which can occur at lower cutting speeds. High speed steel tools may be more economical than carbide, particularly with the possibility of a large rake angle on machines which cannot reach carbide cutting speeds.
