Component Differences

Tin bronze is an alloy composed of copper, tin, and a small amount of phosphorus, iron, nickel, and other impurities. While brass is mainly made up of copper and zinc, and also contains a small amount of aluminum, manganese, lead, and other impurities.

Property differences

1. Corrosion resistance

Tin bronze is more resistant to corrosion than brass and can be applied in harsher environments. The tin contained in tin bronze can enhance the alloy's corrosion resistance, avoiding the problem of copper being prone to oxidation, while brass is more susceptible to oxidation and corrosion.

2. Strength and hardness

Tin bronze is harder and stronger than brass. Due to the tin in its composition, the alloy becomes more hard and wear-resistant, making it more suitable for applications that require frequent use or exposure to high friction.

3. Price

Tin bronze is usually more expensive than brass because the tin it contains is a rare metal, and the processing requires higher technical levels and costs.

Differences in Usage

Tin bronze is typically used in various environments that require resistance to corrosion and wear, such as ships and offshore structures, automotive engines and transmissions, agricultural and chemical machinery, etc. While brass is usually used in situations with lower strength and lower friction, such as flooring and wall decoration materials, faucets, etc.

In conclusion, tin bronze and brass have significant differences in composition, properties, and usage. Each is suitable for different application scenarios. Choosing different materials based on requirements can enhance the performance of the product.

The color difference between tin bronze and brass

Although both tin bronze and brass tend to have a yellowish hue, a closer inspection reveals their distinct differences. The yellow color of tin bronze is usually more profound and has a metallic luster, sometimes appearing golden or bluish. In contrast, the color of brass is relatively brighter and more vivid, presenting the typical brass color. This color difference to some extent also reflects the differences in their composition and properties.
