Product Description

Product Description:

Alumina Zirconia Si3N4 Ceramic Welding Location Pins

Compared with the pins in white zirconia the blue pins' lifespan is at least 40 times longer.
Compared with the pins in black silicon nitride in normal welding condition the blue pins' lifespan is about at least 2 times longer.
Compared with Japanese famous metal pins the blue pins'lifespan is 10 times longer

ceramic weld pin is a standard shape and size for projection welding applications. Ceramic pins provide high durability and reliability at a much lower cost than full ceramic pins, and are less prone to shattering after being mishandled or dropped. Ceramic-coated pins are more durable and cost-effective than anodized steel or KCF, and do not require heat treatment before use.

For dimensions and specifications, see the diagram in the pictures above.
