Based on responsibility and trust, we have succeeded in developing economical and eco-friendly milling process with our own patented technology, and supply special alloy powders to the world.

The melting alloy powder processed in a melting furnace designed and manufactured by BongHwa industry Co., Ltd is integrated with rigidity-enhancing technology- the only patented technology in the nation for the economical and eco-friendly melting composition, including tensile strength, corrosion resistance, and weather resistance.

In particular, we apply advanced melting technology to special welding rod alloy powders used in shipbuilding, aerospace, and defense industries to prevent flow-through and increase weldability.

A patented technology that stabilizes milled alloy powder to release oxygen, nitrogen, and other gases in the metal, thereby improve alloy performance and reduce the amount of gas to secure workers’ safety and prevent environmental pollution at the same time.

A heat treatment process that produces customized special alloys by sintering alloys at higher than 1,000℃ and removing crystal water.
