Stainless steel is an alloy steel that consist of iron and chrome or iron, chrome, and nickel. It is regulated to includes more than 10.5% of chrome and iron content should be under 50%. Generally, we call stainless steel as a perspective from anti-heat and anti-errosion. Stainless steel is difficult to be corroded even in corrosive environment like in the air and even in the water. （Reference）Stainless Steel Anti-Corrosion The term "rusting" refers to a phenomenon in which metalic surface corrodes through complex chemical actions. However, this is not necessarily an absolute chacteristic. For example, a metalli surface may not corrode under a paticular environment but may corrode under different environment. Therefore, it becomes necessary to select the right application suitable for its properties. Ordinary steel will rust when left eposed to the air. This is because steel is oxidized by the moisture and the oxygen in the air. When chromium is gradually added to steel, the resulting material will hardly rust if the chromium level is higher than 12% or so. However, when looking closely at the phenomenon, a thin oxide membrance is being formed on the surface. This film is very tough and adheres firmly to the steel, thereby preventing the progress of oxidation. Even if it is peeled off for one reason or another, a new identical fim is generated immedeiately to over the surface.

Beryllium copper combines high strength with non-magnetic and non-sparking qualities. It has excellent metalworking, forming and machining qualities. Rod is used for engine for air plane, propeller, bolt, cam, gear wheel, bearing etc. Wire is used for coil spring, swirl spring, brush etc. Precipitation hardening treatment(350±5℃×120M)makes the hardness twice the strength. Beryllium copper is a ductile, weldable, and machinable alloy. It is resistant to non-oxidizing acids (for example, hydrochloric acid, or carbonic acid), to plastic decomposition products, to abrasive wear and to galling. Phosphor Bronze Wire Phosphor bronze is an alloy of copper with 3.5 to 10% of tin and a significant phosphorus content of up to 1%. The phosphorus is added as deoxidizing agent during melting. These alloys are notable for their toughness, strength, low coefficient of friction, and fine grain. The phosphorus also improves the fluidity of the molten metal and thereby improves the castability, and improves mechanical properties by cleaning up the grain boundaries C5071 W （PBW-1） C5102 W C5111 W （PBW-2） C5191 W （PBW-3） C5212 W Free-Cutting Phosphor Bronze Wire C5341B Excellent machinability.

Also remarkable is its high density of 19.3 times that of water, comparable to that of uranium and gold, and much higher (about 1.7 times) than that of lead. Tungsten with minor amounts of impurities is often brittle and hard, making it difficult to work. However, very pure tungsten, though still hard, is more ductile, and can be cut with a hard-steel hacksaw.
