【Abstract】 Objective:To study the physical castability of a new type nickel based ceramic alloy without beryllium by comparing with CW PA alloy and VB alloy,for the purpose of future clinical application.Methods:The mesh casting method was used to evaluate this alloy, three kinds of alloys(nickel based ceramic alloy without beryllium,CW PA alloy and VB alloy) were casted into a kind of net on which 100 meshes contacts.The percentage was figured out by counting the casted meshes.Results:The percentage of castability of nickel based ceramic alloy without beryllium,CW PA alloy and VB alloy is respectively 99.92%,100%,100%.Conclusions:The new type nickel based ceramic alloy without beryllium has desirable castability and shows excellent cilincal performance.更多还原
