In many cases complete resistance to cor rosion is highly desirable, and while working to accomplish this result, we discovered that the addition to the other metals of a relativelyrsmall gives the unexpected remarkable eii'ect of such a small amount of platinum, slightincrease in cost, which is t where it is desired to provide an alloy at about the same .or lower cost than the usual sold alloys. We have found that these metals can be comis obtained at only a 1 bined in difl'erent proportions to produce satisis factory alloys.
