In mechanical drawings, what is the technical requirement of an aluminum bar "delivery status: CS"?
When ordering, the delivery status should be marked in the contract.Status of aluminum alloys:R: hot working stateM: annealed conditionY: work hardening stateC: quenching conditionCZ: quenching and natural agingCZY: quenching, natural aging, cold working stateCS: quenching and artificial aging conditionCSY: quenching, artificial aging, cold working stateY2: semi hard stateRCS (T5): air cooling and manual aging

Suitable for solid solution heat treatment, no longer cold processing (or impact on mechanical properties limit of straightening, Jiao Ping), and then artificial aging products.New code name and new and old code name contrast, please refer to "GBT 16475-2008 deformed aluminum and aluminum alloy condition code", online free download (Baidu search: GBT 16475-2008)
In mechanical drawing, there is a technical requirement for aluminium bar, "delivery state: CS", which refers to the delivery of aluminum alloy after heat treatment in the condition of quenching and artificial aging.Delivery status refers to the final plastic deformation or final heat treatment of the delivered product. General without heat treatment delivery says hot or cold drawing (rolling) state or state; after the said heat treatment heat treatment delivery, or according to the heat treatment of the category (Chang Hua), said normalizing tempering, solution and annealing condition.
