Ceramics Heat Extruding Module

Material Property
It has good heat intensity and red hardness, mould thermal stability, good wear resistance, no oxidation, no deformation in high working temperature, no hanging, extrusion products of high precision, good surface quality, high yield, etc

Hardness: hardness in room temperature: HRA in 80-87;Under the temperature 1000℃, vickers hardness HV is more than 400. Therefore, RJT extrusion die in use do not deform. The module hole is stable in die geometry, the extrusion product size ism of high precision. Surface quality is good.

Abrasion resistance: roll wear experiments are taken under the same conditions, RJT mold material abrasion value is only 1/6 of hot steel mold materials (after the heat treatment of 3 cr2w8v)

Friction coefficient 0.266

Linear coefficient: 11.62×10 - 6~12.31×10 - 6 mm/℃

It is mainly used in hot extrusion die of copper and copper alloy. Various types of rod, wire, tubes, special types can be used. It can also be used for aluminium alloy, stainless steel hot extrusion dies. As hot extrusion forming module of copper alloy, ceramics mold’ temperature is between 700℃ to 1000℃.

TIG welding electrodes - Application

TIG welding is under the environment of the inert gas such as argon. The electric arc between tungsten electrodes and parent metal make the parent metal and welding material melting together.

Due to the excellent properties, tungsten is very suitable for the TIG welding electrode materials.

TIG welding electrodes - Material Property
We can improve the welding performance of tungsten electrode by adding rare earth elements such as lanthanum oxide, zirconium oxide, yttrium oxide and thorium oxide, etc.

TIG welding electrodes - Features
− Suitable for almost all industrial metals and alloys

− Highly reliable welding quality

− Good welding shape, no need to remove the slag

− No splash

− Less smoke

− Suitable for different thickness of plate

TIG welding electrodes - Classification
DC TIG welding uses DC power source as the welding power source. Tungsten electrode is used as negative pole, parent metal as positive pole. This method is widely used in stainless steel, titanium, copper and copper alloy welding.

AC TIG welding uses AC power source for welding power source. During the process, negative pole and positive pole keep on changing all the time .When the positive pole was overheated, the oxide layer on the surface of the parent metal would be removed. Base on the cleaning effect, AC TIG welding is widely used in the welding of aluminum, magnesium, and etc.

About us

Company portrait

As a wholly-owned subsidiary of Advanced Technology & Materials Co.,Ltd.(AT&M), ATTL Advanced Materials Co., Ltd. (ATTL) is formed by the merger of Beijing Tianlong tungsten and molybdenum Technology Co., Ltd. And Refractory Materials & Ceramics Branch of AT&M. Refractory Materials & Ceramics Branch of AT&M, whose predecessor is Refractory Alloy Laboratory of Central Iron and Steel Research Institute, was founded in 1958.

As one of the earliest units devoted to the refractory metal material in domestic market, ATTL owns the largest sized and the most advanced manufacture facilities in the domestic refractory metal fields. The main equipment including hot isostatic pressing machine, cold isostatic pressing machine, plasma spraying equipment, vacuum induction sintering furnace, controlled atmosphere heat treatment furnace, high temperature sintering furnace, ultrasonic testing, universal testing machine, three coordinate measuring instrument, TC600C oxygen-nitrogen analyzer, C600C carbon analyzer etc.

ATTL has four R&D manufacturing bases in Beijing Zhongguancun innovation park, Tianjin Baodi economic development zone, Shaanxi Baoji Taibai county economic park and Shandong Weihai industrial new area, of which the total area is nearly 400 thousand m2. Now, treating the refractory metal materials like tungsten, molybdenum, rhenium, Tantalum and Niobium as the main research direction, ATTL constantly provides services to the global high-end market.

ATTL products are widely applied not only in the traditional industries such as aviation, Aerospace, national defense, automobile, electronic and electric power, equipment manufacturing, metal material processing, quartz and glass and glass fiber manufacturing, high-temperature industrial furnaces and electric light sources , but also in the new and emerging ones such as LCD, solar energy, nuclear energy, nuclear medicine, LED lighting, large-scale integrated circuits, new energy vehicles and consumer electronics.

ATTL is committed to provide customers with consistent, reliable, high quality products, prompt deliveries, responsive customer services and to develop mutually profitable partnerships.
