Tin Bronze

Tin bronze is a metal alloy formed basically by the chemical union of copper and tin. Although tin atoms are relatively large compared to copper, the solubility of tin in copper is high.

This property provides the bronze alloy with considerable mechanical strength and hardness, which is one of the main reasons why this alloy is widely used by different kinds of industrial sectors.

Fundição Magma produces different types of tin bronze ingot. Faithful to its strict quality policy, the company maintains strict control throughout the tin bronze ingot manufacturing process. The same zeal is dedicated to its marketing, delivery and after-sales practices and routines.

Appreciation for quality is a fundamental part of our institutional culture.

Tin effect in the bronze alloy

The effect of the presence of tin in the bronze alloy is to increase the copper mechanical strength and hardness. Therefore, the hardness of bronze is directly linked to the concentration of tin in the alloy, which can reach up to 12% of the total concentration.

Bronze alloys with 10% or more of tin are used in the production of parts that require high mechanical strength in order to withstand heavy loads and mechanical wear, such as bearings and bushings for high loads and low speeds. Examples of these alloys:

  • C.A. 90500 (SAE 62 or Bronze 88-10-0-2)
  • C.A. 90700 (SAE 65 or Bronze 90-10)

The types of bronze most used in the industry contain tin in their composition. Our company produces ingots of tin bronze alloys both on demand – adjusting the composition to the customer’s needs – and in accordance with the specificities determined by international standards.

When increasing the content of tin in the bronze alloy, the mechanical strength increases; the ductility, however, decreases, mainly from 5% of tin concentration.

To improve mechanical strength and wear resistance properties, a small percentage of phosphorus can be added. This element also acts as a deoxidizing factor, originating phosphor bronze, such as Bronze C.A. 93200 (SAE 660 or Bronze 83-7-7-3), Bronze C.A. 90300 (SAE 620 or simply tin bronze) and Bronze C.A. 90700 (SAE 65 or Bronze 90-10).

Bronze characteristics

Bronze is one of the oldest alloys used by mankind. Its characteristics are responsible for the use of metal for more than three thousand years – prior, therefore, to the use of iron. It is believed that bronze was discovered by blacksmiths who, faced with the very high demand for copper pieces, tried to increase the volume of the metal by adding tin.

The result was a metal alloy with properties different from and even superior to pure copper, such as, for example, flexibility combined with mechanical strength. In addition, the good castability of bronze allowed the recasting of waste and residues – a practical and economic benefit.

When other elements are added to the tin copper alloy, such as lead, zinc, iron and nickel, bronze alloys are obtained with excellent results.
