Tin Copper Alloy

The chemical union of the metals copper (Cu) and tin (Sn) forms the bronze alloy, a reddish, malleable and ductile metal. Percentages of other metals can be added to the copper and tin alloy to create alternative alloys with different characteristics. Variations are necessary to meet the specific demands of industrial segments, such as electronics, for example, according to the particularities of their products.

A Fundição Magma produces a variety of copper and tin alloys, always within the strictest international standards. The quality control of our products is carried out at all stages of the production process, starting with the careful selection of raw materials and passing through the technical approval of our laboratory. These procedures guarantee the excellence of Magma products.

Cooper and Tin alloy types

In the different types of copper and tin alloys, copper is always the base metal, being present in a greater percentage in all of them. The most common types of copper and tin alloys are:

Cooper and tin alloys with zinc: It contains about 2% zinc in its composition, giving this bronze extra resistance to corrosion. This is because, in the presence of moisture, zinc promotes the creation of a surface layer of corrosion-resistant carbon oxide. After receiving heat treatment, this type of bronze acquires high strength. In addition, they are weldable solderable with phosphatized bronze electrodes.

Copper and tin alloys with lead: They contain lead in their composition in concentrations of 7%, 8%, 12% and 15%. They are also known by the name of red bronze. The mixture of metals in this alloy gives it very peculiar characteristics of mechanical, thermal and chemical strength. They are widely used in the manufacture of artwork industrial parts and musical instruments, among others.

Copper and tin alloys with phosphorus: Also known as phosphor bronze, this alloy has a maximum of 16% phosphorus in its composition. The presence of the phosphorus element gives the alloy excellent machinability, formability and anti-friction properties. This bronze is widely used in the production of equipment that requires long-term lubrication, such as piston rings, hydraulic material, bushings, bearings and gears.

Copper and Tin Alloy Applications

Bronze is one of humanity’s oldest metal alloys. Its manufacture and use go back more than 3 thousand years and it is still widely used in various products nowadays. Some applications of copper and tin alloy:

  • Screws and nuts
  • Tools and equipment for plants
  • Electrical appliances
  • Hydraulic fittings
  • Engine Coating
  • Gears
  • Bells (due to their resonance)
  • Musical instruments
  • Decorative objects (statues and tombstones)
  • Pumps, valves and stop valves
  • Rings, bushings and bearings

The main advantages of copper and tin alloys are:

  • High hardness
  • High melting point
  • High strength
  • High ductility
  • Resistance to corrosion
  • Excellent conductivity of heat and electricity
  • Great finishing capacity
