1. In general‚ why have many different alloys been developed and used? Many different alloys have been developed and used due to the various properties they have when alloyed which increase their amount of uses. Properties such as increased tensile strength‚ the variation in melting point‚ malleability and luster are all properties that come as a result from alloyed metals. For example‚ carbon and manganese form an alloy called carbon steel‚ which is very hard and can therefore be used to make things
