The present invention provides a corrosion-resistant CuZn alloy, the alloy having a Zn content of from 15 to 55% by mass, the balance being Cu and inevitable impurities, wherein a total content of Zn and Cu is 99.995% by mass or more, and wherein a number of pores is 1/cm.sup.2 or less based on optical microscopic observation.

Systems and methods of non-contact tensioning of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor. The magnetic rotor is spaced apart from the metal strip by a first distance. The systems and methods also include tensioning the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is tensioned in an upstream direction or a downstream direction. In other aspects, rotating the magnetic rotor induces a magnetic field into the metal strip such that a force normal to a surface of the metal strip is applied to the metal strip.

A method for manufacturing a golden member includes a first heating step and a second heating step. The first heating step is a step of heating, in the atmosphere of mixed gas including nitrogen gas and water vapor, a raw material member including titanium or a titanium alloy at 670° C. or higher and 730° C. or lower for 150 minutes or more and 200 minutes or less. The second heating step is a step of heating, in the atmosphere of nitrogen gas or in the atmosphere of mixed gas including nitrogen gas and inert gas, the raw material member passing through the first heating step at 670° C. or higher and 730° C. or lower for 30 minutes or more and 120 minutes or less so as to obtain a golden member including titanium or a titanium alloy.
