WebMar 13, 2013 · Nickel Magnesium (NiMg) master alloy is one such product offered by KBM Affilips. NiMg Composition of NiMg The following alloys and composition are possible: Nickel-magnesium (5%, 15% and 20% Mg) Nickel-magnesium-iron Nickel-magnesium-silicon-iron Nickel-magnesium-cerium (MM) Nickel-magnesium-silicon-cerium (MM)-iron Magnesium alloys harden rapidly with any type of cold work, and therefore cannot be extensively cold formed without repeated annealing. Sharp bending, spinning, or drawing must be done at about 500 to 600 °F (260 to 316 °C), although gentle bending around large radii can be done cold. Slow forming gives better results than rapid shaping. Press forging is preferred to hammer forging, because the press allows greater time for metal flow. The plastic forging range is 500 to 800 °F … georgetown university easter break
