Bronze Silica Sol Investment Casting

The copper alloy cast with ZCuSn10Pb5 has high corrosion resistance, especially for dilute sulfuric acid, hydrochloric acid and fatty acid. ZCuSn10Pb5 cast copper alloy is used for structural materials, corrosion-resistant and acid-resistant accessories, as well as crusher bushings and bearing bushes. After more than 20 years of precipitation, Qinhuangdao Zhongwei Precision Machinery Co., Ltd. has rich experience in the production of various grades of brass, tin bronze castings, silicon bronze, aluminum bronze and other castings. Expect producers from various countries to consult Tin Bronze Silica Sol Investment Casting.

Process Classification

Tin Bronze Silica Sol Investment Casting

Standard GB/T 1176-1987

Casting method: metal mold casting

Material name: (10-5 tin bronze, metal type)

Grade: ZCuSn10Pb5

ZCuSn10Pb5 cast tin bronze

Casting method:

S-sand casting, J-metal casting, La-continuous casting, Li centrifugal casting

The representation method of cast copper alloy grade is "ZCu+ main addition alloying element symbol and mass fraction+ other elements and mass fraction+.... For example, ZCuZn38 represents cast copper-zinc alloy (brass), in which the mass fraction of zinc is 38%, the remainder is copper.

Application

Tin Bronze Silica Sol Investment Casting is mainly used for explosion-proof tools, molds, structural parts of submarine cable repeaters, welding electrodes, etc. Cast tin bronze, cast aluminum bronze, and cast brass are mainly used as bearing bushes, bushings, bushings, bearings, gears, pipe fittings, etc. Cast copper alloys are widely used in arts and crafts, ancient bronzes being a typical example.

In the defense industry, it is used to manufacture bullets, shells, gun parts, etc. For every 3 million rounds of bullets, 130-140 tons of copper are needed.

In the construction industry, it is used as various pipes, pipe fittings, decorative devices, etc.
