Each block weighs approximately 4.1lbs (3.9lbs to 4.1lbs) and measures 1" x 4" x 4". A good gravity casting alloy, ZA-8 is rapidly growing in popularity for pressure die casting. ZA-8 can be hot chamber die cast, with improved strength, hardness and creep properties over other Zamak's, with the exception of a No. 2 alloy which is very similar in performance. ZA-8 is readily plated and finished using standard procedures for Zamak. When the performance of standard No. 3 or No. 5 is in question, ZA-8 is often the die casting choice because of high strength and creep properties and efficient hot chamber castability.
