Product Name:

Cast Tungsten Carbide

Model:

Description:

Metal tungsten and tungsten carbide powders as raw materials are mixed，packed in a graphite boat, melted in a melting furnace at about 3000℃，and held for a certain time to obtain alloy casting block of cast tungsten carbide with phase diagram of W2C and WC and particle size of 1-3µm. Particle are silver grey with metal luster. Cast tungsten carbide is applied by oxygenace-tylene flame,arc,spray, braze and wet welding on wear places.It is also adhered firmly to the surface of wear work pieces with epcxy resin and inorganic additives at lower temperature and impact.The parts of build-up cast tungsten carbide coating can stand with high temperature and impact.It is characterized by long tool life,easy maintenance,low coat and improved productivity. In the production,whether equipment normally run is dependent on materials wear resistance for wear parts in great degree.Selection of materials with better wear resistance provides longer equipment-life and stable running. Cast tungsten carbide as a wear material is widely used in the mining,petroleum,construction and agricultural machinery and steel industry etc.because of its high hardness (HRA 93.0~93.7),good wear resistance,easy build-up welding and low cost.

Product Name:

Cast Tungsten Carbide Welding Rod

Model:

Description:

Application:Cast Tungsten Carbide Welding Rods are mainly used as Pile-Up welding on the surface of metal parts to enhance its wearability.General YZ20-30g with thick electrode surfacing work and work requirements from Scraping role of the parts and components; If required welding layer 3 to 4 mm, multi-electrode used YZ30 - 40g; Surfacing request thin layer formation, the best choice YZ40 - 60g or more granular tubular alloy electrode.

Product Name:

Metal Bonding

Model:

Description:

Applications: Diamonds bit bonded metal is widely used binder, mainly composed of Cu, Ni, Mn, Zn,Cu and Ni which play a major role in bonding, Mn in the sintering process on the one hand a bit deoxidation, on the other hand has also been increased by bit wear resistance and hardness. Zn in the sintering process bit main function is to increase the mobility of bonding metal to uniform distribution in diamonds bit matrix organization.
