What are Metal Parts?

What exactly does Metal Parts mean?
Metal Parts is often shorthand for "Metal Parts." They refer to components made from metals such as iron, copper, aluminum, stainless steel, and alloys through processes like casting, forging, cutting, and stamping. These components range in size from screws and washers a few millimeters to machine tool housings and automotive chassis components several meters long. They are the building blocks of industrial products.

What are the common material classifications for Metal Parts?
They are mainly divided into two categories: ferrous metal parts, which are based on iron, such as cast iron (machine tool bases and valves; low cost and good rigidity), carbon steel parts (bolts and gears; high strength and easy machining), and stainless steel parts (medical devices, kitchenware; corrosion resistance); and non-ferrous metal parts, which are based on non-ferrous metals, such as aluminum and aluminum alloys (aviation parts, mobile phone cases; lightweight and thermally conductive), copper and copper alloys (wire connectors and heat sinks; excellent electrical and thermal conductivity), and zinc alloy parts (hardware accessories, toys; easy to die-cast).

What role do metal parts play in industry?
They are the cornerstone of industrial production: they form the backbone of equipment, such as automobile engine blocks and machine tool spindles; they transmit power and motion, as seen in gears and bearings, which transmit motor power to actuators, enabling equipment operation; and they ensure precision and durability. Precision parts (such as instrument pointer shafts) determine equipment accuracy, while high-strength parts (such as track shoes for construction machinery) extend equipment life.
