1.CLAD MATERIALS
　　As the experience of that the founder have provided Fujitsu with silver clad on phosphorous bronze and silver clad on brass in 1954 tell you, our pioneer has been making effort in the development of new techniqes for clad materials.
　　The market demand has changed after suffering from the first oil shock and enormous increase of the cost of precious metals. Customers want us to produce less thickness of precious metal layer such as few microns. In other words, they tend to use less and only minimum required amount of precious metals.
　　According to the development in technology of semiconductors industries, the needs of the time come to require compactness of the parts; small size, light ant thin materials. We have been coping with the requirements of such materials which are highly qualified and varied in types but small in quantities by facilitating our plant with more tooling machines.

2.BRAZING ALLOYS
　　Brazing is a metal joint technique which does not melt the base metal. We have been manufacturing silver brazing alloy for highly qualified use, phosphor copper brazing alloy for joining copper alloys, and other improved brazing alloy. Current production volume is approx. 50 tons a month and it makes us as the biggest brazing alloy manufacturer.
　　Particularly our tri-metal clad, made of silver brazing alloy on both side of copper and phosphor copper brazing matal on both sides of copper, get a popularity in highly reliable and rational use.

3.MATERIALS FOR COMMUTATOR OF PRECISE MICRO-MOTORS
　　Micro-motors have been in general use of most of all electric appliances. Currently required is the micro-motors which are smaller, more precise and more durable with the severe working condition compared with what previously used for machineries and automobiles.
　　Toyonaga Electric Lab. Co., which is one of the leading companyin this field today have been cooperating with us to develop the materials for such varied micro-motors. The products made under this cooperation have been employed by Matsushita Electric Industrial Co., Ltd., Victor Company of Japan Co., Ltd., Hitachi Co., Ltd. and etc.
　　It is no exaggerate to say that such matal materials which developed by Toyonaga and us are still covering almost all materials used in this field. We can meet every need or requirement in shapes and forms; such as strip, pipe, clad style and etc.
　　You can find a huge number of micro-motors used in your VTR, radio-cassette tape recorder, electric shaver, automobile, electric juicer and other household electric appliances or industrial machineries including robot.
