Refractory metals are a class of metals that are extraordinarily resistant to heat and wear. These materials must be chemically and physically stable at high temperatures. Depending on the operating environment, they need to be resistant to thermal shock, be chemically inert, and/or have specific ranges of thermal conductivity and of the coefficient of thermal expansion.
Some of the materials that Asia Technic offers are commercial grade nickel-iron-chromium alloy, stainless steel, tungsten alloy, aluminium alloy, that is known for its intrinsic formability and corrosion resistance of aluminum is needed while high strength is not.
Example applications include chemical and food handling, sheet metal, hollowware, heat exchangers, and lighting. Titanium Grades 1, 2, 3, 4, 7, 11, and 12 are all considered unalloyed and have similar mechanical properties. Applications: Airframe components, cryogenic vessels, heat exchangers, CPI equipment, condenser tubing, pickling baskets.
