· JVASP-110291· AlCr6Si

AlCr6Si is an aluminum-chromium-silicon alloy that combines aluminum's light weight with chromium and silicon additions for enhanced wear resistance, oxidation resistance, and strength at elevated temperatures. This alloy family is typically used in engine components, wear-resistant coatings, and thermal barrier applications where the base aluminum matrix requires significant hardening. The chromium-silicon combination is particularly valued in automotive and aerospace sectors for components that must withstand both thermal cycling and mechanical wear without excessive weight penalty.

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.
