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. |
