COPPER /BRASS / BRONZE Copper is not magnetic. Brass is a mixture (alloy) of copper and mostly zinc (zinc is not magnetic). Bronze is a mixture (alloy) of mostly copper with about 12% tin, and sometimes small amounts of nickel (nickel can make it very slightly magnetic but, generally...
Alloys- mixtures in which the main element (or, usually, elements) are metal(s). A more technical definition of an alloy is 'a partial or complete solid solution of one or more elements in a metallic matrix'. Common examples of alloys include bronze, brass and steels. When alloys are sp...

A solution is a mixture of one substance dissolved in another so the properties are the same throughout. A solution is composed of a solute and the solvent. The solute is the substance being dissolved and the solvent is the part of the solution that does the dissolving. The solute is of...
metals. They cannot be separated into their individual components by physical methods. Irrespective of that, an alloy is considered as a mixture. It is because an alloy shows the properties of its constituents and can have variablecomposition. For example, brass is a mixture of 30%zincand 70%...
