induction braze copper tube to brass fitting

Objective To use induction heating to braze a copper tube to a brass fitting using a preform braze wire. Processing is to occur under an atmosphere of Nitrogen and 4% Hydrogen gas. The braze preforms melt at 1190F, but the parts need to be kept below 1300F…

induction brazing copper tube

Objective To braze a copper tube ( 3/8″ OD by 2-4″ long) into a 3/8″ fitting in less than 10 seconds. Heating must take place in a channel type coil to allow for easy loading of parts. Material Copper Tubing and Fitting with Braze and Stay Silv White…

induction annealing copper tubing

Objective To heat both ends of a copper tube to anneal as soft as possible 1.5” (38.1mm) from end and retain full hardness next to anneal Material 1.625” (41.275mm) dia x 24” (609.6mm) long copper tube Temperature 1500 F (815.5 C) Frequency 70 kHz E…

induction tempering of steel

The tempering of hardened steels is surely one of the most important of industrial heat-treating operations. For this reason, the mechanisms underlying the process as well as the effect of tempering on final mechanical properties have received wide attenti…

hardening and tempering of tool and die steels

Tool and die steels are covered in BS 4659:1989,although both American nomenclature and a variety of trade names are also in use. Available in high-quality grades, these specifically-designed steels can be grouped broadly according to their intended applic…
