Fasteners made from Promal are heat-treated, malleable castings. Top plates are manufactured from cast Promal and deliver abrasion resistance in corrosive environments such as coke and sinter operations. Bottom plates are manufactured from steel. Available in select sizes in some fastener families.
Copper and silicon alloy for use in grain elevators and other potentially explosive environments. Spark-free material compared to steel but fully non-magnetic. Also for belts with magnetic pulleys or separators.
Features superior resistance to wear and abrasion. Provides several times the service life of steel. Not recommended where impact or corrosion is a problem. Available in select sizes in some fastener families.
