Seria1N0.71,806 6 Claims. (01. 138-47) This invention relates to improvements in corrosion-resistant tubular articles, and more particularly, corrosion-resistant wrought-metal tubular articles formed of copper-base alloys con- 5 taining phosphorus, aluminum and tin, with or without the addition of one or more other elements which do not seriously impair the prop saline liquid or dilute acid. The additional elemerits may range up to a total of about 10%, depending on what elements are added, some being more innocuous than others. While each of the elements iron, antimony and arsenic should not be present much in excess of about 0.1%, silver, which is comparatively innocuous, may be present to as high as about 10% provided not too much of other elements is present. Nickel may be present to as high as about 5%, and lead and silicon may each be present to ashigh as about o o In order that our improved alloys may be wrought to make tubular articles such, for ex- 35 ample, as tubes, pipes, etc., for conveying or holding or otherwise contacting corrosive liquids, the total of the phosphorus, aluminum and tin preferably should not be greater than about 7 with the phosphorus from about to about 2%, the aluminum from about to about 4%, and the tin from about to about 3 Stillbetter workability of the metal is had when the total of the phosphorus, aluminum and tin does not exceed about 5 /2%, with the 45 phosphorus from about to about 1' /2%.' the aluminum from about A% to about'3%, andthe tin from about to about 2%.
An advantageous alloy range consists in having the phosphorus from about. /2% to about 55 phorus, about 7 aluminum and about 3% tin, 1
the second having about 1% phosphorus, about 1% aluminum and about 2% tin, and the third having about 1% phosphorus, about 1 alu minum and about 1 tin. v
The invention maybe carried out in other specific ways than those herein set forth without departing from the spirit and essential char- 1 1. acteristics of the invention, and the present embodiments are therefore to be considered in all respects as illustrative and not restrictive, and all'changes coming within the meaning and equivalency rangeof the appended claims are,-
intended to be embraced therein.
We claim: a V
