Properties of metals
Metals have properties that distinguish them from other materials. The most important of these properties is strength, or the ability to support weigh without bending or breaking. This property combined with toughness, or the ability to bend without breaking, is important. Metals also have advantages regarding resistance to corrosion. They are responsive to heat treatment.
Metal can be cast into many shapes and sizes. They can be welded, hardened, and softened. Metals also possess another important property-recycling and reuse. When a particular product is discarded, it can be cut into convenient sections. These sections can be put into a furnace, remelted, and used in another product.
The properties of metals may be classified in three categories: chemical properties, mechanical properties, and physical properties. Here we will emphasize the primary mechanical properties of metals. In understanding the related areas of metalworking and methods used today, the mechanical properties of metals are of the utmost importance.
The hardness of metals varies greatly. Some, like lead, can be indented easily. Others like tungsten carbide, approach diamond hardness. They are of great value as dies for cutting tools of various types. Heat treatment causes change in the hardness. Annealed tool steel can readily be machined. Often, this is difficult after it has been hardness and tempered. Annealed brass is comparatively soft. When cold-worked the hardness is greatly increased.
A tough metal possesses very high strength. It also has the capability to avoid deforming permanently and resist rupture. Toughness enables the metal to survive shock or impact without fracture.
The strength of a metal is its ability to resist deformation or rupture. In certain items, a combination of strength and plasticity is desirable. Machine tools are an example.
