Name:  HSi80-3 silicon brass
Model:  
Brand:  Brass category
Standard:  GB/T 13808-1992
Description:
On the basis of copper and zinc alloy, adding brass silicon. It is in the atmosphere and seawater have high corrosion resistance, resistance to stress corrosion cracking than the general brass. Silicon content is generally below 4%. Common silicon brass 80Cu-17Zn-3Si can withstand hot pressure processing, excellent corrosion resistance, tensile strength of the soft state of 300MPa, elongation of 58%, for the production of ship parts, steam pipes and pipe fittings. This alloy of lead content should not exceed 0.01%, otherwise it will damage the thermoplastic, especially forging performance. 65Cu-31.5Zn-1.5Si-Pb for lead-free silicon brass, with high cutting resistance, friction reduction and corrosion resistance, mainly used for wear-resistant bronze substitutes.
Property
HSi80-3 silicon brass has good mechanical properties, high corrosion resistance, corrosion cracking tendency can wear in cold, hot, good under pressure processing, easy welding and brazing, cutting good. Thermal conductivity is the lowest of brass. [1]
Use
HSi80-3 silicon brass ship parts for steam pipes and pipe fittings.
