What Does 7075 T651 Mean?
7075 identifies the aluminium alloy composition, with zinc as its principal alloying element.
T651 identifies the temper condition. The material is solution heat treated, artificially aged and stress relieved by controlled stretching. This helps reduce residual stresses and improves dimensional stability during machining.
This makes 7075 T651 Round Bar particularly useful for components where maintaining dimensional accuracy during machining is important.
