Wenzhou Saijin Electric Alloy Co., Ltd. (referred to as Saijin) specializes in producing all kinds of contact rivets, contact points, contact components, electrical accessories and silver alloy wire. Next, introduce two of the products.

1. Nickel plated blind contact rivet

Nickel-plated blind contact rivets are made of copper. Copper is second only to silver, superior to all other metals, and is therefore used as a benchmark for the electrical conductivity of materials. Not only copper has excellent electrical conductivity, but also has a high melting point (1083 ° C), good mechanical properties, corrosion resistance, reliable operation and long service life, making it the most widely used conductive material.

Nickel-plated blind contact rivet electrical contact elements are widely used in switches, relays, thermostats, contactors, disconnectors, controllers, timers and other low voltage equipment.

Material properties

• Copper content (% by weight): ≥99.90
• Density (g/cm3): 8.89
• Reactance rate (μΩ·cm): ≤0.0177
• Hardness HV (MPa): ≥ 65
• TensileStrength (MPa): ≥295
• Elongation (%): ≥3

2. AgSnO2In2O3 solid contact rivet

AgSnO2In2O3 solid contact rivet is made of AgSnO2In2O3. AgSnO2In2O3 has high arc corrosion resistance and good contact solder resistance. By introducing certain additives, AgSnO2 materials produced by powder metallurgy techniques can be modified in such a way that contact resistance and over-temperature behavior can be kept low and stable over the lifetime. Material transfer in DC operation is low. The AgSnO2In2O3 contact material is non-toxic and environmentally friendly.

AgSnO2In2O3 solid contact rivets are widely used in a variety of contactors, relays, circuit breakers and switches.
