PAM(Plasma Arc Melting)

Hello. We are Dong-A Specialty Metals Co., Ltd. At our Haman plant, we operate advanced Plasma Arc Melting (PAM) equipment to produce raw materials for steelmaking and alloy manufacturing. With this, we complete the value chain—from recycling rare metal scrap to producing high-performance ingots.


What is Plasma Arc Melting (PAM)?

Plasma Arc Melting is a state-of-the-art metallurgical process used to melt and refine high-melting-point and reactive metals, such as titanium and nickel-based alloys. PAM utilizes a plasma arc torch that generates extremely high temperatures—exceeding 15,000K—in a controlled atmosphere of inert gas, typically argon or helium.

This advanced method ensures minimal oxidation and contamination, delivering high-purity titanium alloys with precisely controlled chemical compositions.


Our In-House PAM & ISM Hybrid Equipment

At Dong-A Specialty Metals, we have developed a hybrid continuous melting system that combines PAM and Induction Skull Melting (ISM). This proprietary equipment allows us to:

  • Continuously melt titanium sponge or scrap

  • Remove internal impurities efficiently

  • Produce titanium and nickel ingots with dimensions up to 230mm x 3000mm

This capability has positioned us as a leading titanium recycler and manufacturer in Korea, attracting both domestic and international interest.


PAM: Key Features and Benefits

✅ Large-Scale Production Capacity

Our facility can process:

  • 560 kg of titanium

  • 980 kg of nickel

per batch in ingot form.


✅ High Alloy Purity

The inert gas environment and controlled pressure (400–1,200 mbar) prevent contamination and preserve the quality of volatile alloying elements like aluminum and vanadium.


✅ Ideal for Aerospace & Automotive Applications

Titanium alloys and titanium aluminides created via PAM offer high strength-to-weight ratios and corrosion resistance, making them ideal for high-tech industries.


✅ Enhanced Scrap Utilization

By recycling titanium scrap and turning it into secondary raw materials, we contribute to sustainable resource circulation and carbon neutrality.


Strategic Applications

Our PAM-produced ingots are further processed into:

  • Titanium rods and wire

  • Nickel-based superalloy components

  • High-performance composite materials

These products are supplied to industries across aerospace, automotive, energy, and advanced manufacturing sectors.


At Dong-A Specialty Metals, we pride ourselves on being at the forefront of titanium recycling and ingot production. Please feel free to reach out to us with inquiries—we are ready to help your company achieve material sustainability and technological advancement.


Thank you.
