Melting temp of chromium
WebThis study determined the effect of various durations of induction melting of a cobalt-chromium alloy on resistance to deflection fatigue. Commercial cobalt-chromium alloy was melted by high-frequency induction for various lengths of time before it was cast into the shape of a denture clasp. WebChromium reacts directly with fluorine, F 2, at 400°C and 200-300 atmospheres to form chromium (VI) fluoride, CrF 6. Cr (s) + 3 F 2 (g) CrF 6 (s) [yellow] Under milder conditions, chromium (V) fluoride, CrF 5, is formed. 2 Cr (s) + 5 F 2 (g) 2 CrF 5 (s) [red]

WebHere’s a graph of the melting point for an alloy of lead and tin: you can see that the lowest melting point is at around 75% tin and 25% lead. This is the eutectic point for the lead-tin binary alloy. Of course, you can have an alloy with more than 2 base elements. http://www.gotrawama.eu/Siderurgia/The%20Thermochemistry%20of%20Transition%20Metal%20Carbides.pdf
