metal

· JVASP-39103· SiMo

SiMo is a silicon-molybdenum alloy or composite material that combines the hardness and thermal properties of silicon with the strength and ductility contributions of molybdenum. This material family is used primarily in high-temperature structural applications and wear-resistant components where conventional steels reach their performance limits, particularly in aerospace, automotive, and industrial machinery sectors where thermal stability and corrosion resistance are critical.

Regulatory Screening

Environmental

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
