1. Tin Bronze
.... Tin bronze has better corrosion resistance and abrasion resistance than brass. For this reason,
.... bronze of within 10% Sn is generally used for all kinds of machine parts and for other arts and crafts.
.... Bronze with 1~2%Sn is used for transmission lines requiring strength and abrasion resistance.
.... Because Bronze with 3~8%Sn and 1%Zn is easy to engrave and mold, it is usually used for money
.... or medal making. Materials adding 4~6%Zn and 4~6%Sn have excellent pressure resistance,
.... abrasion resistance, machinability, and cast-ability.
.... Product use : Valves, pump bodies, impellers, water-supply facilities, bearings, sleeves`,
...,......................... bushing and General Machinery, etc.

2. Phosphor Bronze
.... When a very small amount of phosphorus (P) is added, liquidity of the smelting furnace is improved,
.... the hardness and strength of alloy is increased, and abrasion resistance and elasticity is enhanced
.... in Bronze.
.... Product use: Pump parts, gears, parts for ships, parts for chemical machines which use corrosion
....................... resistance and abrasion resistance, and processed goods such as plates and wires
....................... that use high elasticity, etc.

3. Lead Bronze

.... Bronze containing 3-26% of Pb among tin bronzes is called Lead bronze.
.... Lubricating ability of Lead Bronze is good because lead exists in boundaries of the grain, which is
.... employed in the structure. Therefore, it is used for a materials which a cutting processing is requested.
.... Product use: It is widely used with bearing, bushing, and packing.

4. Aluminum Bronze
.... Compared to brass or tin bronze, Aluminum Bronze is a relatively new alloy and, compared to other
.... copper alloys, is excellent in its mechanical attributes and corrosion resistance.
.... Product use: Propellers for ships, turbine parts, etc.

5. Silicon Bronze

.... Less than 4% Si is used for silicon bronze, and it is used for structural materials because the strength is
.... similar to wrought steel and corrosion resistance is good.
.... Product use: Storage tanks, bolts, nuts, piston rings, etc.
