CAC301 to CAC304, a basic introduction to four different types of high-strength brass



There are four types of high-strength brass models, namely: CAC301 type (original JIS symbol: HBsC1); CAC302 type (original JIS symbol: HBsC2) CAC303 type (original JIS symbol: HBsC3); CAC304 type (original JIS symbol: HBsC4) . This article describes the basic applications and properties of four high-strength brasses. Among them, CAC304 model high-strength brass is currently the most widely used one. Jiaxing Gurun can provide various types of CAC304 high-strength brass products.
1. CAC301 type (original JIS symbol: HBsC1)
