Zhengzhou Lepe Refractory Materials Co.,Ltd. was established in 1996 and has been engaged in the production of electric heating elements for more than 20 years. The factory is located in Gaoxin Industrial Park, Dengfeng City, Henan Province, only 13 kilometers away from Shaolin Temple, the birthplace of Shaolin martial arts.

Our main products are MoSi2 heating element, SiC heating element, tungsten and molybdenum products. The products are widely used in ceramics, glass, powder metallurgy, refractory materials, metal materials, chemicals, aerospace, research institutions and other fields. Our The company has a complete production line and technology research and development center, a sound quality management and quality assurance system, product quality is stable and reliable. Through the unremitting efforts and coordinated development of all employees of the company, the products are constantly improved and updated. Recently we have developed a new product - silnitride molten aluminum heater. At the same time, we are also developing high quality other tungsten and molybdenum products.

We will continue to provide customers with quality electric heating materials and perfect after-sales service. Thanks to all our customers for making our products available to more than 50 countries and regions around the world.

Thank you for choosing the high quality products produced by LEPE®. We sincerely welcome people from all walks of life at home and abroad to visit and guide us. We are willing to provide you with more services.

Tungsten Products

Tungsten powder with purity greater than 99.95% can be used to produce tungsten wire, tungsten rod, tungsten plate, tungsten sheet, tungsten foil, tungsten crucible, etc. after high-temperature sintering. And also can produce a variety of tungsten parts after machining.

Tungsten copper alloy

The tungsten-copper alloy is an alloy composed of tungsten and copper. The copper content of common alloys is 10% to 50%. It has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At very high temperatures, such as above 3000 ° C, the copper in the alloy is liquefied and evaporated, which absorbs a large amount of heat and lowers the surface temperature of the material. So this type of material is also known as metal sweating material.

SiC heating element

LEPE® SiC heating element is a rod-shaped and tubular non-metal high-temperature electric heating element made of high-purity green hexagonal silcarbide as the main raw material, processed into a billet at a certain ratio, and recrystallized and sintered at a high temperature of 2200 °C. The normal use temperature in the oxidizing atmosphere can reach up to 1450 ° C, and the continuous use time can reach 7000 hours.

MoSi2 heating element

LEPE® MoSi2 heating element can reach 1800°C under oxidizing atmosphere, suitable temperature 1000-1700°C.

Molybdenum products

Molybdenum is a silvery white refractory metal. Molybdenum has a melting point of 2620 ° C, a boiling point of 5560 ° C, and a density of 10.2g /cm3. It is easily oxidized at normal temperature. Molybdenum has a high hardness and a Mohs hardness of 5 to 5.5. The heat of vaporization of molybdenum at the boiling point is 594kJ/mol; the heat of fusion is 27.6±2.9kJ/mol; and the heat of sublimation at 25 ° C is 659kJ/mol. Molybdenum can increase the high temperature strength and toughness of steel.
