Brazing alloy and brazing paste for gas container joints

摘要

Component parts of a steel container for storing a gas, specifically a mixture of stabilized methylacetylene and propadiene (C3H4), are joined by a brazing alloy consisting of about 48% to 67% by weight copper; about 4.5% to about 7% by weight phosphorous and the balance nickel. During manufacture of the container, component parts may be joined either by brazing the joint with the specified alloy in wire or rod form or by applying to the joint a brazing paste comprising the specified metals unalloyed in powdered form and heating the joint in a furnace to melt and alloy the metals to form the joint. The brazing alloy has desirable metallurgical characteristics and is nonreactive to exposure to the specified gas stored in the container. The brazing paste has characteristics which enhance its utility for mass production techniques.
