Introduces some of the products

OA device components
Fin tubes
Plate type heat exchanger

We supply various materials and parts from heat sink until photo sensitive drum pipe.Pull out tubes, used for photosensitive drum in copiers, are required high dimensional precision and surface quality. We supply raw material for these tubes that match these high requirements.

Our aluminum an copper are used for various parts mounted in home use air conditioners, up to heat exchangers in industrial plants.Our aluminum coils for fin materials are optimized mixing of additives in order to improve heat exchange rate; They have higher thermal conductivity than conventional ones.

Plate type heat exchangers perform reliable heat exchange as high and low pressure fluids flow on opposite sides of the plates.

LED lighting
Rice cookers
Appliance housings and panels

Our aluminum parts are also used for heat-dissipating plates in LED lights.

Compared to a rice cooker made only of stainless steel, a rice cooker that is made using SUS/AL clad materials is lighter in weight, has better thermal conductivity and better rust resistance. So it is used for the inner pot in the rice cooker.

Pre-coated aluminum materials covered with a coating that dissipates heat rapidly are used to make the panels for home appliances.It also dissipates heat from electronic equipment.
