The appearance: Tungsten Rod is divided into forging bar and polished rod; the forging bas surface is allowed to have oxidize film and slight forging hammer mark;polished molybdenum bar surface presents metallic luster and has no obvious oxidized phenomenon.
The two surfaces have no defects, such as divided layer, crackle, burr and vertical crackle, etc.
The specification: The tungten rod diameter and length deviation are consulted by both parties according to GB4188-84 standard or user's demand.
Main application: Tungsten Rod is used for making electric vacuum device and electric light source parts.
Tungsten rod and tungsten plate produced by our company can be widely used in semiconductor ion injection parts:
Tungsten and molybdenum products used in ion implantation machine have stable high purity and good mechanical properties to ensure that they are suitable for machining arc chamber parts with complex shapes.
The high purity tungsten and molybdenum arc chamber is the basic guarantee for the yield of semiconductor chips.
Our high-performance ion injection Source Head tungsten and molybdenum components greatly reduce the maintenance frequency of the machine, ensure the customer productivity, and is the best choice for customers.
Wroughted/Straightened/Ground
Large stock , fast delivery(for ISO standard diameters).
100% Quality guarantee.
