Tungsten carbide rod hardness test mainly adopts Rockwell hardness tester to test HRA hardness level. This is a kind of non-destructive test, and is relatively easy to operate. This kind of detection method has small testing force and little indentation, high measuring speed and high efficiency; therefore, it can be directly used to test finished products.

Hardness test has certain similarities with tensile test, both of which are used to test the resistance capability of metals to plastic deformation. Because tensile test is a kind of destructive test, so hardness test is adopted more frequently than tensile test.

Tungsten carbide measuring rod is used to detect inner bore of products using tungsten carbide bars of certain established specifications. With the hardness of 90HRA, tungsten carbide measuring rod has excellent abrasion resistance, long service life, low coefficient of thermal expansion, and is less susceptible to damage and endure high temperature. Its life expectancy is 20-30 times longer than that of steel.

There are four main measuring projects of tungsten carbide measuring rods: aperture, hole center distance, hole position and hole inclination.

Tungsten carbide square rods are long rods with rectangular cross section, also known as tungsten carbide bar. Both its processing technology and performance are the same as tungsten carbide round rod. It has high hardness, abrasion resistance and impact resistance.

Tungsten carbide square rod has good versatility and is easy to weld, and thus suitable for processing wood, non-ferrous metals, cast iron, hardened steel, PCB, etc., and can also be used to manufacture various types of motors, dies and punches.

Tungsten faceted beads have flat surfaces, facets if you get it, create more reflective surfaces and thusly little shiny glaring spotlights underwater of supreme fish attractiveness.

Flies tied with faceted tungsten do sparkle a little more and have a distinctive look about them. Tungsten faceted beads have been shown to catch 1.7 times more fish than non faceted beads and the tungsten’s properties make these beads sink faster and deeper to where the really gigantic and voracious fish live.

Tungsten faceted beads are available in basic tasteful colors of black, gold, est., and cover the basic sizes from 7/64 oz to 5/32oz.
