is gold brittle?If not why then it is mixed other metals ?

gold is extracted as a jelly like substance. it undergoes various processes to become a harder one. we are mixing other metals with it because a pure gold ornament which is known as 24 carat is too costly to afford. so some amount of copper or other metals are mixed with it to get some cheaper kinds of gold ornaments

gold is extremely ductile-meaning that it can be drawn out into wire or threadlike forms without becoming brittle and breaking. It is said that gold can be drawn out so thin that a single ounce could be made to stretch a continuous length of 35 miles.
