· AlSn

AlSn is an aluminum-tin binary alloy that combines aluminum's light weight and corrosion resistance with tin's softness and low melting point characteristics. It is used primarily in bearing and bushing applications, solder formulations, and low-temperature joining where the reduced melting point and improved machinability of the tin addition provide advantages over pure aluminum. Engineers select AlSn alloys when moderate strength combined with excellent wear resistance and ease of casting or forming is needed, particularly in applications where thermal cycling or thermal management is a secondary concern.

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.
