Metal brazing – tips and advice | Johnson Matthey

For some appliions a colour match between the brazing filler metals and the parent metals is clearly desirable. The following SILVER-FLO alloys should be considered.. SILVER-FLO 60, 56 and 55 are silvery in colour and are suitable for use on nickel silver or stainless steel provided that there is no danger of interfacial corrosion ; SILVER-FLO 20, 18 and 16 are more yellow or brass coloured.

Why Does Silicon Carbide Have A High Melting Point? …

Its melting point is 2730 degree C, which is quite high. The reason for the high degree in temperature was that despite being covalently bond, it also has a ionic bond with it, which positive and negative ions attracting each other.

Quick Answer: Can Tungsten Cause Cancer? - Ceramics

Does carbide cause cancer? Calcium carbide is known to cause cancer and also causes food poisoning, gastric irritation and mouth ulcers. According to scientists, when calcium carbide comes in contact with moisture in the atmosphere, it produces acetylene gas, which like ethylene accelerates the ripening process.

Silicon_carbide

Silicon carbide fibers produced on a tungsten core of 12μm diameter show a thin interfacial layer between the silicon carbide mantle and the tungsten core, caused by chemical interaction between the silicon carbide and tungsten, which forms reaction products of α-W 2 C and W 5 Si 3. Heating above 900°C leads to growth of this reactive layer and degradation of the properties of the fiber.
