Unfortunately you are right. I visited a customer of mine early last week and they were putting together a manifold for cooling water lines on a machine that had to ship before Christmas. He had ordered some brass fittings - push on hose barb to NPT male thread - I believe they were 1/2" x 1/2". He tossed me one and said what do you think..?. I wasn't sure what he was referring to. Then he tossed me another one. Both were the same size, but one was noticeably heavier than the other. The lighter one had a heavier wall through the fitting but it was quite a bit shorter and the color of the brass was a very light color - almost like it was some type of Alum alloy. The other piece was machined out of brass hex bar and was full length. The first one was a Chinese made fitting that they had first received. The second one was from a US maker. He said they began using the US made fittings after they found out that the Chinese made fittings would twist off when tightened. The inferior fittings came from a national distributor who I am sure thought that they had gotten a very good price on some brass fitting.
I have no idea what alloy they were but obviously they were of inferior quality.
