· JVASP-156441· AlSnAu

AlSnAu is a ternary aluminum-tin-gold alloy that combines the lightweight and corrosion-resistant properties of aluminum with tin's strengthening effects and gold's superior electrical and thermal conductivity. This material is primarily explored in microelectronics and precision bonding applications where reliable electrical contacts and high thermal management are critical, offering advantages over conventional Al-Si or Al-Cu solders in specialized contexts requiring enhanced performance at interfaces.

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.
