BS EN 12420 is a European standard on copper and copper alloys that discusses the requirements and characteristics of copper and copper alloy die and hand forgings.
BS EN 12420 specifies the composition, the property requirements, and tolerances on dimensions and form for copper and copper alloy die and hand forgings.
The sampling procedures, the methods of testing for verification of conformity to the requirements of BS EN 12420, and the delivery conditions are also specified.
BS EN 12420 on copper and copper alloy die and hand forging are relevant to:
Copper and its alloys exhibit good ductility and are generally considered as easy to forge. Copper alloys have good plasticity and strength, good abrasion resistance and thermal conductivity, especially good corrosion resistance in air and seawater.
BS EN 12420 provides guidance on material condition, chemical composition, mechanical properties, electrical properties, resistance to dezincification, residual stress level, tolerance for die forgings, tolerance on dimensions, surface quality.
As a user of BS EN 12420, you can be ensured of the requirements and characteristics of copper and copper alloy die and hand forgings. With obedience and compliance to BS EN 12420, you can efficiently manufacture high-quality copper and copper alloy die and hand forgings. BS EN 12420 exemplifies the chemical composition, mechanical properties, and electrical properties that help you achieve precision in terms of product functionality and specification. BS EN 12420 provides you with comprehensive information useful throughout the process of production.
