have been present since the establishment of the company in 1960, with the support of everyone.
At present, we mainly handle metal materials such as stainless steel,
high alloy, titanium, aluminum and copper.
Furthermore, cutting, machining and welding were carried out on the material,
We also undertake a number of engineering tasks such as manufacturing products.
It is our mission and growth opportunity to respond to customer's needs
faster and more accurately.
We have evolved in response to customer needs, including the handling of valves,
silicon wafers, telescopic fittings, insulation materials, motors, etc.,
renewal acquisition of ISO9001 (2015), expansion of sales offices.

The main event best was promoted to the chief from sales staff, business tour of the air show in Paris, and the world's pretty pet became a member of the family. My boom is stress striking with stewed dishes from kneading food! Even if it looks like it is a heart of glass so do not have power hurdles, therefore handling precautions! The mission strives to be thanked to customers by balancing the two pillars of aircraft and semiconductor parts, and by a hybrid of seriousness and warmth during calm and passion.
The main event best was returning to the company and the first business trip to India on business, the work environment has improved and feels challenging. My boom keeps weight loss and health care by running! It is unexpectedly bored personality, it is best when we received orders for projects involving two or more companies and thanked our customers for quick delivery! I will do our utmost to satisfy customers, including mending efforts not only for material sales but also proposing work for processing to material sales destinations.
The main event best was promoted to the chief by sales representative, moving for the fifth time in life. My boom climbing / camping, breeding / observation of pet (turtle) and cultivation of avocado (thinking)! Actually, I do not care much about miscellaneous things. It seems to be listening but I have not hear about it actually if I do not like it I will be silent. but since my soliloquy is increasing and I am looking for a partner who can discuss with ease comfortably. The mission is looking for what comes to "best match" for myself. (Sales method
The main event best was engagement of my daughter 's engagement, joining Inoue, that the youngest child who became a social worker last year grew up to be a sociable person. My boom is go to Kyoto every year since last year. Despite being brought to my wife, every time I go, I feel deeper and the number of trips also increases!The company is something I do not know without entering it, it was nice to meet a good company at the end of my work life. The mission is to sell aluminum materials, cultivate the demand market, get to know the latest information equipment quickly, and feel rewarding with encounters with new people.
The main event best is finally a longing admirer of Tokyo (independence), flying to Hawaii for the first time in 10 years at a friend's wedding ceremony. My boom finally completed 1000 puzzles (surprising though it is a leisure person). Nature is somewhat twisted and chattery, but I feel challenging when it is said that thank you from customers and sales. Mission is support behind sales, but we will challenge deepening of sales jobs and improving English proficiency and communication skills.

Wrought copper
Wrought copper is made of brass with zinc added to copper, phosphor bronze with tin and phosphorus added, copper alloy such as western white with nickel and zinc added, hot or cold such as melting, casting, rolling, drawing and forging It is a generic term for products processed into shapes such as plates, strips, pipes, bars, lines, etc. by plastic processing. It has high conductivity and thermal conductivity, it is excellent in durability and color tone, and it is used in a wide range of applications. It is a material with high demand such as air conditioning (copper pipe) and electronic parts (lead frame of semiconductor).

Aluminum
We, Inoue corporation has become a need for the era in lightweight performance improvement, and now aluminum is used in transportation fields such as automobiles, railroad vehicles, aircraft, vessels, containers and so on. In addition, by taking advantage of lightness, various effects such as increasing the work efficiency of high-speed rotating parts and sliding parts of various machines, suppressing the weight increase due to the increase in size of the equipment, etc. are bringing various effects. Aluminum is easy to use because it is light in weight because it is lightweight, has properties that it is easy to process, such as being soft and malleable, and because of the oxide film that can be formed on the surface, the ionization tendency is large, and corrosion resistance There is also.
The specific gravity of aluminum is 2.7.
It is about 1/3 compared with iron (7.8) and copper (8.9).
