U-shaped silicon molybdenum rod: U-shaped design element is the most commonly used one. The heating end is welded to the end of the cold end, and the diameter of the cold end is twice the diameter of the hot end. This specification is the most commonly used specification, and is generally used for vertical suspension.

　　When customizing products, customers need to provide the required product's heating end diameter, heating end length, cold end length, and center distance parameters.

　　Silicon molybdenum rod resistive heating element is a resistance heating element made of molybdenum disilicide with high temperature resistance and oxidation resistance. When used in a high-temperature oxidizing atmosphere, a bright and dense quartz (SiO2) glass film is formed on the surface, which can protect the inner layer of the silicon molybdenum rod from oxidation, so the silicon-molybdenum rod element has unique high-temperature oxidation resistance.

　　The standard specifications are: d1x d2: Φ3/6, Φ4/9, Φ5/10, Φ6/12, Φ7/14, Φ9/18, Φ12/24 and other specifications.

　　U Shape, Material Grade 1800, D1=3mm, D2=6mm, Le=140mm,

　　Lu=125mm, A=25mm

　　Specify：18, U, 3/6×140×125×25
