Product Series
Tungsten Wire Rope for Monocrystalline Silicon Growth Furnaces
Product Introduction
1. Purity of tungsten wire rope: 99.95%
2. Good mechanical properties: high temperature resistance, wear resistance, corrosion resistance, tensile resistance, etc., mainly used in smelting and casting, single crystal furnace equipment and other smelting applications.
Product Application
Tungsten wire rope is an important part of the single crystal silicon crystal extrusion system, which requires sufficient high temperature tensile strength and straightness to ensure long-term stability and reliability of crystal growth.
