Titanium (Ti)
Titanium is a lightweight metal with high strength, excellent fire resistance, and corrosion resistance. It is widely used in aircraft components, medical implants like artificial joints, and high-performance sports equipment. In the chemical industry, it is also used as material for reactors and piping. An alloy of titanium and nickel, known as a shape-memory alloy, is used in products such as eyeglass frames.

Cobalt (Co)
Cobalt is a silvery-white metal that is more resistant to oxidation than iron and is also resistant to acids and bases. Cobalt is not used on its own but is utilized to enhance corrosion resistance, heat resistance, and wear resistance. Recently, it has been increasingly used in the production of cathode materials for lithium-ion batteries and in the manufacturing of hard alloys, with demand rapidly expanding.

Tungsten (W)
Tungsten has the highest melting point and is the hardest metal among all metals, making it a primary component in hard alloys. It is indispensable for applications requiring high hardness, such as drill bits and cutting tools. Additionally, due to its low environmental impact and high radiation shielding capability, it is also widely used in medical fields such as X-ray and CT scanning.

- High-Speed Steel (HSS)
- Target
- Catalyst
Tantalum (Ta)
Tantalum is a shiny silvery-white metal and one of the rare metals. With the third highest melting point (2997°C) after tungsten and rhenium, tantalum is also ductile and can be processed at room temperature. It is extensively used in the chemical industry as material for experimental equipment and as a substitute for platinum.

Molybdenum (Mo)
Molybdenum is a type of rare metal with a high melting point, strength, and rigidity. It is used as an additive for steel, and some stainless steels contain molybdenum. Metals alloyed with molybdenum exhibit increased hardness and impact resistance, making them valuable for experimental parts in the automotive industry and rocket components in the aerospace industry.
