· Zn

Zinc is a ductile transition metal widely used as a protective coating and in brass/bronze alloys rather than as a pure structural material. It is primarily specified for corrosion resistance in galvanizing applications, sacrificial anode systems, and die-casting due to its excellent atmospheric corrosion protection and ease of processing. Engineers select zinc coatings over bare steel for outdoor infrastructure, automotive components, and hardware when long-term durability in corrosive environments is required, and select zinc alloys when dimensional precision and complex geometries are needed at moderate cost.

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.
