Product Description

 

Spherical Cast tungsten carbide powder

Cast Tungsten Carbide (WC) Appearance:
Dark gray powder spherical smooth particles
Feature:
High temperature resistance, super wear resistance and impact resistance.
Application:
Widely used in mining oil, metallurgical industry, construction machinery, agricultural machinery and steel industry, used in oil drilling industry such as PDC drill bits and other infiltration manufacturing products. It can be used in the machining center of the cutting scraper drill bit roller cone bit combined with the mechanical industry for surface reinforcement.
Introduction:
Hardness: 93-93.7
Microhardness: 2500-3000kg/mm2
Density: 16.5g/cm3
Melting point: 2525 ºC
purpose
Used as a material for reinforcing the surface of petroleum drilling tools, building materials machinery, grain machinery, and other easily worn parts for surfacing welding.
Performance: Gray particles, gray powder.
Folding organizational structure
1. The cross-section structure of cast tungsten carbide should be uniform, dense, and with consistent luster, and there should be no under burning or over burning phenomenon. The section of high carbon cast tungsten carbide shall not have severe overburning or other phenomena.
2. The metallographic structure of high carbon cast tungsten carbide powder packed products (YZGf): The eutectic needle like structure of (MWC+NW2C) shall not be less than 75%.
The appearance of cast tungsten carbide alloy powder is silver gray, with a polygonal shape. The majority of particles have a length and width less than 2:1, and there is no accumulation of micro powder on the surface of the particles.
