Alumina Ceramic Sintering Setters For Electronic Component

Alumina Ceramic Sintering Setters For Electronic Component

High purity alumina setters are ideal for quality improvement and cost reduction.
Since high purity Alumina has excellent corrosion resistance and thermal shock resistance, it is used for setters for sintering and heat treatment.

Main features

• Sintering ceramic setters for electronic component materials
• Ceramic setters for heat treatment of metal products
• Ceramic jigs for brazing process, etc.
