Tin bronze rod parameter table

Tin bronze rods are mainly used in the electrical industry for manufacturing wear-resistant components and conductive elements. Specific applications include:

Wear-resistant components

The tin bronze rod, due to its high strength and wear resistance, is often used to manufacture mechanical transmission components such as bearings, shaft sleeves, and gears, and is suitable for scenarios with high loads and frequent friction.

Conductive components

Contact components: such as spring contacts, conductive brushes, etc., must take into account both conductivity and wear resistance.

Electromagnetic shielding material: Some tin bronze rods, due to their good processing properties, can be made into electromagnetic shielding materials and used for protecting electronic equipment.

Heat dissipation components

In the connection terminals of equipment such as motors and transformers, the tin bronze rods, due to their excellent heat-conducting properties, can effectively conduct heat and prevent local overheating.

During the manufacturing process of resistors, electric heating elements and other electrical components, the materials not only need to have excellent electrical conductivity and thermal conductivity, but also must maintain stable performance over a long period of time in harsh environments such as high temperatures, humidity and corrosive conditions.
