High functionality, low precious-metal content, and reliability TANAKA seeks to unlock the unlimited potential of precious metals.
Precious metals inherently possess excellent characteristics such as the following: contact reliability in harsh conditions; oxidative resistance in high temperature conditions; high activity that accelerates chemical reactions; and resistance to high-voltage discharges. To these characteristics, TANAKA adds the functions required for automotive materials and offers our customers new added value from development to function assurance.
