Item # BrazeIt 30
Brazeit 30 is historically a modification of Brazeit 35 with a further reduction in silver content resulting in a higher melting point and a longer melting range (185 ºF). Brazeit 30 is used for brazing steel, stainless steel, copper, copper alloys, nickel, nickel alloys or combinations of these metals. It is similar to Brazeit 35 in performance although it contains less silver. Its broader melting range is helpful where clearances are not uniform. During melting, Brazeit 30 passes from the solid state to mushy or a plastic state and progressively to a liquid. If heated slowly through this plastic state (1125-1310 ºF) the liquid portion may flow from the solid portion. This causes a separation of the alloy into a low temperature melting (fluid) portion and a high temperature melting (solid) portion. This phenomenon is called liquation. The high temperature melting portion will melt only above the normal brazing temperature of Brazeit 30. For this reason, Brazeit 30 should be heated rapidly through the melting range.

Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys close joint clearances.
Less silver than Sil. 35 at the expense of increased melt temperature and range.
Standard forms of Brazeit 30 are wire, strip and preforms.
Brazeit 30 contains cadmium and therefore upon heating may produce toxic fumes. It is essential that adequate ventilation be provided so that personnel will not inhale gases and fumes while brazing. The operation and maintenance of brazing equipment or facility should conform to the provisions of American National Standard (ANSI) Z49.1, "Safety in Welding and Cutting." For more complete information refer to the Material Safety Data sheet for Brazeit 30.
