Aluminum : Common grades include 5052, 6061, 7075, etc., which are used in automotive parts, electrical equipment, and cookware. They have many advantages, including a good strength-to-weight ratio and high electrical conductivity.

Carbon steel: Carbon steel is used in a range of products in both industrial and consumer markets. It is a steel alloy that contains carbon, and after heat treatment, the hardness and strength of the material increase.

Copper: Examples of products made from copper are gutters, roofs, rain gutters, and doors. Copper has higher electrical and thermal conductivity than aluminum, but it is also more expensive.

                                                                                                          

Galvanized steel: Galvanized steel is often used to make car bodies, water pipes, fences, roofs, and stairs. It is made by applying zinc to steel through a hot-dip process, which helps make it more corrosion-resistant.

High-strength steel: Military armor plates are often made from high-strength steel. The material is made by alloying steel with a range of elements such as carbon, manganese, and copper. This helps increase its hardness.

Stainless steel: Common grades include SUS304/SUS316, etc., which are used in kitchen containers, chemical storage tanks, and food processing machinery. Stainless steel has excellent corrosion resistance, fire resistance and heat resistance, strength-to-weight ratio, and manufacturability.

                                                                                                                     

Titanium : Typical products made of titanium include aviation parts, medical equipment, and building elements. It is mainly used for its high strength-to-weight ratio and corrosion resistance.
