Multi-functional and High quality ceramic tube heater alumina ceramic with multiple functions made in Japan
Because of superior insulation resistance in high temperatures,
and excellent high frequency characteristics,
our products are used widely as components in various heat treatment manufacturing processes,
solar batteries, liquid crystals, and semiconductor manufacturing equipment.
Because of a high degree of hardness, super abrasion resistance, and high mechanical strength,
our products are used in various construction materials and slide members.
With extreme heat resistance, our products are also usable in temperatures of 1,700-1,800℃.
Additionally, given a high thermal conductivity, and the possibility of thin-walled molding,
they are used actively as parts in various kinds of sensors.
Because of resistance to chemicals and corrosion, and superior chemical stability,
our products are also used variously as components in vacuum chambers, bulbs, pumps,
nozzles, and even in biomaterials.
Our high purity dense alumina products are widely known as our most highly circulated fine
ceramics, and our company has received a favorable reputation for our abundant standard
inventory. With PTO (extrusion material), PTC (press/cold isostatic press material),
PSO (cast material), and PS3N (cast material), we are able to support a variety of goods.
Like sapphires and rubies, alumina is a crystalline form of corundum (α-Al2O3).
We also provide general-purpose dense alumina with reduced purity.
In addition to variations including purity levels of 92%, 96%, and 98%,
we have colored alumina in variations including chromium pink, manganese pink, red,
dark brown, black, and pale blue, so we are prepared with choices to meet clients' demands.

We “Agency Assist Inc.” is specialized in trading high quality processed metals. Since our company was founded in 1990, We’ve contributed to create a market as a supplier of Japanese industrial products and technology. We’ve also aimed to spread the market to overseas and our goal is to be a top of metalworking trading company in Japan.
However, we’ve been working not only as a supplier but quality manager of products. Most of all are inspected by hand with testing tools. Depending on the products, we check over the products with some machines such as CMM, image measuring instrument and so on before sending and delivering. In other words, we always provide reliable and high quality parts to our customers. Although it takes time and effort to check a lot of products, we believe that the continued effort makes customers satisfied. Moreover, it’s been making good relationship of trust with our customers for a long time.
As you know, it’s one of the most important elements for buyers to cooperate with Japanese companies because most of them are always careful about their jobs. However, it’s hard for them that have much chance to contact with such good companies. On Alibaba, we believe that we can probably solve the problems. We will search and provide Japanese industrial products which buyers want. We will also suggest which can handle as much as possible in Japan. We “Agency Assist Inc.” will going to be the bridge between Japan and foreign countries through the Alibaba.
