ASTM C37800 Lead Brass Seamless Tubes For Mechanical Manufacturing
Industry
1. Description
ASTM C37800 lead brass has high strength and good hot working
performance. It is widely used in mechanical manufacturing
industry, cutting various parts and standard parts.
C37800 lead brass beryllium copper alloy is a kind of high brass
alloy, which can be divided into wrought beryllium brass alloy and
cast beryllium brass alloy according to the different processing
forms of its obtained shape; according to the beryllium content and
its characteristics, it can be divided into high strength beryllium
brass alloy and high conductivity beryllium brass alloy.
