(măgnā´lē m)
, alloy of aluminum and about 5% magnesium. Although weak and soft in the elemental state, magnesium alloys with aluminum, manganese, zinc, tin, zirconium, and cerium to produce alloys useful in engineering materials. The strength and hardness of aluminum increases when it is alloyed with such substances as magnesium, manganese, nickel, chromium, zinc, iron, copper, and silicon. Magnaliumlighter and more workable than aluminumis used in making metal mirrors and scientific instruments.
