Alloys find a host of application in various industries and domestic use. Alloying of metals helps to improve the physical and chemical properties of such materials better. Some materials are alloyed to improve their strength. Alloying can help heat and electrical conduction of a substance. Alloys can greatly prevent rusting and produce corrosion resistant metals. Alloys can provide a better means for a material to be worked. Alloys can be more durable than original materials.
