Import Ed/Db/U/W Type Sic Heating Elements — Buy in Bulk from Supplier in China

The ED/DB/U/W type silicon carbide heating element is a rod-shaped, non-metallic electrical heater manufactured from high-purity green silicon carbide through high-temperature silicification and recrystallization. It operates at temperatures up to 1,620°C and is designed for industrial furnace applications requiring oxidation resistance and long-term stability. The element has a cold resistance of 0.5 to 2.5 ohms, depending on diameter and length, and is available in standard diameters from 6mm to 18mm.

These elements are distinguished by their low thermal expansion, high thermal conductivity, and resistance to chemical corrosion in oxidizing atmospheres. Unlike metallic heaters, they do not oxidize or degrade at high temperatures and can maintain structural integrity over thousands of heating cycles. The standard production method involves recrystallization to form a dense beta-SiC structure, which enhances mechanical strength and electrical stability under load.

This model is commonly used in laboratory furnaces, ceramic kilns, sintering ovens, and glass processing equipment. Buyers include industrial manufacturers, research institutions, and equipment integrators. The elements are typically supplied unmounted, with terminal ends prepared for nickel alloy connections. Packaging is in cardboard boxes with foam inserts, with minimum order quantities starting at 10 units. Lead time is 20 to 30 days after order confirmation.

Zhengzhou Mingxin Electric Heating Elements Co., Ltd is a manufacturer located in Dengfeng, Henan Province, specializing in silicon carbide heating elements. The company is registered with a verified factory address and operates as a harbor-tier supplier. No public information is available regarding years in business, workforce size, production volume, or client list. The listing does not mention certifications, ISO status, or export experience.

The supplier focuses on the production of standard ED/DB/U/W type SiC elements using traditional recrystallization methods. There is no indication of custom design services, prototype development, or in-house material testing labs. Buyers should assume the product is made to common industry specifications rather than proprietary standards. Quality control appears to be based on dimensional checks and resistance testing, with no mention of thermal cycling or creep resistance validation.
