Aluminum is very lightweight material (specific gravity : 2.7) compared with steel (specific gravity : 7.9)
By this special character,Aluminum is very useful to produce lightweight products such as many kind of mobile instrument and the commodities needed lightweight such as many types of vehicle and production machineries for corresponding to save energy and environmental needs.
Aluminum has been increased demand for clean room use by good resisting character of less getting rust.
This material is now specially noticed in spotlight as the material of the environment friendly metal due to possible to be recycled easily at low cost.

Stainless steel is very famous material which is added Nickel and Chromium to steel element and evaluated widely as 'the steel of less stain or less rust' from many fields.
Stainless steel has been used extensively in food processing machineries and kitchen utensils and also handrails, monuments as ornamental use by without any painting.
Furthermore this material has been increasing consumption to use for machinery parts and this is the special material having high possibility to be used in many fields.

This material are very familiar metal for many years to have been used since long time ago,for example this was used for casting famous the Great Buddha of Nara.
This material has been used widely in many applications because of high electrical conductivity and high thermal conductivity and having good durability and sperior to good color tone.
Recently this matrial has been used a lot for air conditioner parts (copper tube) and electronic parts (leadframe for semiconductor).

This is a kind of improved steel group and one example is the steel with high hardness by adding Carbon element, we have large variety of stock of various types of special steels in accordance with many applications.
This material is naturally used for cutlery and many types of tools, and also for mold use with high hardness specially for the super presision mold use of IT related commodities has widely used in recent years.

We handle many kind of plastic materials from the multipurpose plastics (vinyl chroride, acryl resin etc.) to the engineering plastics.
The engineering plastics which was specially produced with high hardness and made high resistant to thermal and chemical substances are used for wide variety of applications by many beneficial characters such as very lightweight compared with metals.

HAKUDO developed original own producs by tied up with many suppliers of both domestic and overseas and sell them under the name of HAKUDO original brand.
Now we are selling YH series, HNS303 and HA series.
YH series provides high accuracy of thicness of alloyed alminum plate.
HNS303 provides excellent free cutting quality of stainless steel plate.
HA series provides specially processed plate of alloyed Aluminum, Stainless steel, Phosphor bronze which is free from working strain made by special heat treatment for the stress relief.
