· JVASP-106847· AlSiMo

AlSiMo is an aluminum-silicon-molybdenum alloy that combines aluminum's light weight with silicon's wear resistance and molybdenum's strength and creep resistance at elevated temperatures. This alloy is typically used in applications requiring good castability, moderate-to-high strength retention, and dimensional stability, particularly in automotive and aerospace components where thermal cycling or elevated-temperature service is a concern. The molybdenum addition distinguishes it from conventional Al-Si alloys by providing enhanced hardness and heat resistance, making it a candidate for engine blocks, cylinder heads, and other powertrain components that experience thermal stress.

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.
