Metal powder metallurgy is a manufacturing technology that implements a range of unique material properties and product shapes by compressing metals or metal oxide powder in a mold and heating and sintering them at high temperatures.
ApplicationsBased on years of accumulated metal powder manufacturing technology, Chang Sung directly designs, develops, and produces the raw materials suitable for the required characteristics of the powdered metallurgy products to produce higher-quality powder metallurgy products.

Magnetic materials are the basic materials of the industry, which have been in the spotlight as a future growth industry thanks to recent advances in electric and electronic technology. Especially soft magnetic materials are being used to amplify the flux density produced by magnetic fields because they provide a high self-reliance, low coercive force, and low hysteresis loss. Chang Sung is able to mass-produce the magnetic components with excellent magnetic properties in a variety of shapes based on the world's leading manufacturing technology for soft magnetic powder cores and metal powder and powder sintering technology.
