Super Metal Industries manufactures wires and strips of various non ferrous metals which includes, copper and phosphor bronze. While copper is a natural mineral, phosphor bronze is an alloy. Hence both the metals vary in chemical, physical and mechanical properties.
Copper:
- Copper is a pure chemical element and a natural mineral that can be found mainly in the earth’s crust and water in smaller quantities.
- Copper is an excellent electrical and thermal conductor. It also has numerous applications in various fields.
- Copper can be easily and readily soldered and brazed easily with other metals and also can be welded by various arc, gas and resistance methods. Moreover, it can be polished and varnished to obtain desired luster appearance.
- Composition:- Copper is naturally present in the earth’s crust as a mineral. So It is available in any composition by adding non metal with it.
- Excellent heat conductivity
- Excellent electrical conductivity
- Good corrosion resistance
- Good biofouling resistance
- Good machinability
- Retention of mechanical and electrical properties at cryogenic temperatures
- Non-magnetic
Phosphor Bronze:
- In contrast, phosphor bronze is an alloy which contains copper as the main constituent with tin and some other metal and non-metal compounds
- Phosphor Bronze alloys have a range of various types, with different compositions; so that different alloys have different properties and applications.
- Phosphor Bronze is a metal alloy containing copper as the main constituent and tin about 12%. Some other metals and nonmetals or metalloids are also added, depending on the requirements, to obtain desired properties.
- Composition:- Copper, Tin ( 0.5% to 7%), phosphorous (0.01% to 0.35%).
- Excellent elasticity.
- High strength.Outstanding malleability for bending and drawing.
- High electrical conductivity.
- No seasonal cracking or age hardening.
- Non-magnetic.
- Easy plating.
- High resistance to chemical corrosion.
