1050A (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.
Our knowledgeable staff and resident metallurgists will be pleased to assist you further on any technical topic. Smiths Metal Centres Limited also boasts an in-house UKAS Accredited Testing Laboratory
which is unique within the multi-metal and plastic stockholding sector. We believe this underlines our total commitment to quality and our ethos of being the complete service provider.
