Strength of TANAKA

Tanaka Kikinzoku Group started life as a money exchange business dealing precious metals in Tokyo in 1885. Since then, we have supported social development through the supply of industrial products made from precious metals.
In 1907, we successfully established the commercial production of platinum filaments used in light bulbs. Later, we produced contacts for communications equipment, crossbar contacts for telephone switchboards and other products mainly made from precious metals. We have commercialized ultrafine gold wire for bonding, catalysts for automotive sensors and exhaust gas purification, catalysts for fuel cells, crucibles used to produce sapphire substrates for LEDs, etc. and are now working to develop and commercialize precious metal materials.
Under the slogan of "Mastering Precious Metals," through business activities involving the research, development and stable supply of materials with focus on precious metals, we will proactively take measures to tackle environmental issues, energy problems and pollution, contributing to the creation of a prosperous society and a beautiful future for the Earth.

Foundation for the Group's Activities

TANAKA's activities are based on the eight precious metal elements of platinum (Pt), gold (Au), silver (Ag), palladium (Pd), rhodium (Rh), iridium (Ir), ruthenium (Ru) and osmium (Os). Industrial precious metals products account for 70% of our business activities. TANAKA's products play active roles in a wide range of items used in our daily lives such as home appliances, information technology devices and automobiles.

Processing to manufacture electrical contacts, printed wiring boards, chemical compounds, catalysts, bonding wire, plating solution, plating equipment, etc.
Precious metals recycling
Recovery of products that are no longer useful to society to recycle them as bullion
Ultimate Cost Reduction Method: Recycling

Valuable precious metals create value only when they are effectively used. To recycle precious metals contained in a product that has reached its end, they usually have to be traded through a market or processed into a form capable of being physically handled first. The former incurs a cost to go through the market (spread, or difference between the selling and buying prices) and the latter generates extra lead time due to the processing and distribution.
Tanaka Kikinzoku Group offers a fully integrated, one-stop service. We do everything from bullion procurement to material processing, manufacturing, sale and recycling, without trading in the market. This provides our customers with shorter lead times and a reduced cost of procuring bullion. In addition to used industrial products, waste scraps and bullion attached to equipment generated during the manufacturing process can also be recycled, which is also an ultimate cost reduction method.
