Tungsten Alloy Non-Magnetic Alloy

Non-magnetic alloy
Non-magnetic alloy, it is to point to no or weak magnetism of cemented carbide materials.
Non-magnetic alloy, it is to point to no or weak magnetism of cemented carbide materials.Due to the production of magnetic materials forming mold requires use of non-magnetic materials, in the past have been use magnetic steel, the mould performance is poorer, hardness is low, service life is short, and the use of a period of time after the mold wall serious galling, deformation, etc., will affect the dimensional accuracy and surface quality of the magnetic material.Now the non-magnetic cemented carbide, with its superior performance instead of no magnetic steel can exponentially improve work efficiency.

Tungsten nickel and iron
Tungsten nickel and iron is a kind of tungsten as base (about 90-98%), and nickel, iron, copper or other alloy components, typically accounts for 17.0 ~ 18.5.
use
Tungsten nickel and iron application, consumption has become the largest main tungsten heavy alloys.As a general application, such as weight, balance weight, anti-radiation shielding device, etc., are directly using the sintered alloy;But if as the application of high mechanical properties, tungsten nickel and iron alloy deformation processing and heat treatment is needed in order to achieve improved.
Tungsten nickel and iron is mainly used in the manufacture of aviation and space flight for the gyroscope rotor, guide and shock absorbing device, etc.;Die mold, knife holder for machinery manufacturing, boring bar and automatic watches a heavy hammer, etc.;Use of conventional weapons of penetrator bomb core, electrical products with rivet head and switch contact;Also used in the manufacture of all kinds of anti radiation shielding components, etc.

Tungsten steel
Tungsten steel (carbide) has high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and a series of excellent properties, especially its high hardness and wear resistance, even under the temperature of 500 ºC is basic remains the same, there are still very high hardness at 1000 ºC.
Carbide, tungsten steel, also known as refers to contain at least one metal carbide sintering of composite materials.Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide, a common component of tungsten steel.Carbide components (or phase) of the grain size is usually between 0.2 and 10 micrometers, carbide grain use metal binder together.Binder usually refers to the metal cobalt (Co), but for some special purpose, nickel (Ni), iron (Fe), or other metal and alloy can also be used.For a backlog of carbides and the composition of the binding phase is called "brand".
The classification of the tungsten steel according to ISO standards.This classification is based on the workpiece material kind (such as P, M, K, N, S, H type).Binding phase composition mainly is to use its strength and corrosion resistance.
Tungsten steel substrate consists of two parts: part of hardening phase;The other part is a metal bonding.Bonding metal is iron group metals commonly, commonly used is cobalt and nickel.So there will be a tungsten cobalt alloy, tungsten cobalt tungsten nickel alloy and titanium alloy.
Containing tungsten steel products, such as high speed steel, and some steel, tungsten steel contains on the steel hardness and heat resistance performance has significantly improved, but the toughness will decline sharply.
