Tin Bronze Sheet

Product Descriptions

Tin bronze is renowned for its exceptional strength, elasticity, wear resistance, and diamagnetic properties. It exhibits excellent pressure processing capabilities, both in hot and cold states, and demonstrates high resistance to electric discharge. This material is also weldable and suitable for brazing, with good machinability and resistance to corrosion in atmospheric and freshwater environments.

 

As a significant metallic material, tin bronze possesses distinct characteristics and advantages in terms of its chemical composition and physical properties. Its primary components are copper and tin, often supplemented with elements like nickel, manganese, and cobalt, alongside trace impurities such as iron and lead. Physically, tin bronze boasts high strength and hardness, coupled with excellent ductility and toughness. Additionally, it offers superior thermal and electrical conductivity, making it a versatile and reliable material for various applications.

Manufacturing and Processing

• Casting

Tin bronze is cast into ingots or slabs, which are then rolled into sheets.

• Rolling

Hot or cold rolling processes are used to produce sheets of desired thickness.

• Annealing

Heat treatment is applied to improve ductility and reduce internal stresses.

• Finishing

Sheets can be polished, coated, or treated for specific applications.

 

Properties of Tin Bronze Sheets

• Corrosion Resistance

Excellent resistance to corrosion in marine, chemical, and industrial environments.

Ideal for use in seawater, acids, and other corrosive media.

• Wear Resistance

High wear resistance makes it suitable for sliding or bearing applications.

• Mechanical Strength

Good tensile strength, fatigue resistance, and hardness.

• Machinability

Can be easily machined, especially when lead is added to the alloy.

• Thermal and Electrical Conductivity

Retains moderate thermal and electrical conductivity, though lower than pure copper.

• Ductility

Can be cold-worked or hot-worked into sheets, strips, and other forms without losing its properties.

• Aesthetic Appeal

Attractive golden-brown color, making it suitable for decorative applications.

 

Advantages of Tin Bronze Sheets
