Alloys
Alloys are metallic materials made from a mixture of two or more metallic or non-metallic elements. Compared to pure metals, alloys usually have superior mechanical and process properties and are relatively inexpensive. In engineering, the most commonly used alloys are iron-carbon alloys based on iron, such as carbon steel, alloy steel and cast iron. There are also aluminum or copper based alloys such as brass and bronze. These alloys are widely used because of their specific properties and uses.

Cast Iron
Cast iron is a mixture of carbon, silicon and iron, characterized by excellent fluidity and ease of casting into complex forms. The fluidity of this metal is largely due to its high carbon content, which exists in the form of both graphite and iron carbide, giving cast iron excellent wear resistance. Cast iron is commonly used in the manufacture of sewer covers, manhole covers, gutter covers, etc. It is also used in the manufacture of mechanical parts such as gear box bodies, machine tool beds, and hydraulic cylinders. To prevent rusting, a bituminous coating is usually added to the surface of the castings.

Aluminum (AL)
Aluminum is a slightly bluish white metal that does not have a long history compared to gold. In engineering, aluminum is usually used in the form of alloys because alloys have better mechanical and process properties than pure aluminum and are less expensive. Aluminum-based alloys, such as brass and bronze, are common metal materials. These alloys often have specific application and performance characteristics that make them useful in a wide variety of engineering and manufacturing applications.

Stainless Steel
Stainless steel is an alloy made by incorporating chromium, nickel, and other metallic elements into steel, which provides excellent corrosion resistance. The corrosion resistance of this alloy is mainly attributed to the element chromium. When the chromium content reaches 12% or more, stainless steel can effectively resist corrosion by the atmosphere and certain chemical media (such as acids). In the field of decoration, stainless steel is mainly used for the production of plates, which are selected for their smooth and shiny surface properties. In addition, through surface treatment, such as coloring disposal, you can obtain a variety of colors of stainless steel, both to maintain its original corrosion resistance, but also to enhance the decorative effect.
