PALIS SILVER 15	15	80	5	650-800	L-Ag15P	BCuP-5
	It has low melting point with good flow. Used where narrow joint include uneven junctions, refrigeration industry, on parts such as cuplings, manifolds, brass distributors, capillary pipes. Has good mechanical characteristics at low temperature.

PALIS SILVER 6	6	88	6	695-795	L-Ag50Cd
	It is with low melting range where temperature is a factor. Fast flow, very fluid at brazing temperature and will penetrate joints with small clearances.

PALIS SILVER 5	5	89	6	650-810	L-Ag5P	BCuP-3
	It is same as Silver 15 and economic. Used largely in the refrigeration and air conditioning industry.

PALIS SILVER 2	2	91.5	6.5	650-810	L-Ag2P	BCuP-6
	It fills moderate gaps in poorly fit joints and has good flow. It has the ability to fill wide joint clearances at the lower end of its brazing range. At the high end of the brazing range, it is more fluid. Recommended for sanitory and refrigerating installations.

Pali sliver 43Cd	43	16	20	615-620	-	-
	this has the shortest range of n=any sliver brazing alloys. this alloy is regarded as the best brazing alloy by menu braziers. it is particularly recommended where a minimum brazing temperature is desirable to preserve the properties of the parent metals, idea where joints have a close fit up and will produce neat joints with optimum ductility and strength.

PALIS SILVER 1	-	92.7	7.3	705-800	L-CuP7	BCuP-2
	It is a low cost alloy with wide melting range and low fluidity. Used in sanitory, refrigeration and air conditioning industry.

PALIS SILVER 2	-	93.8	6.2	710-880	L-CuP6	-
	It is the most economical and used where the joint clearance is wider. Flow is sluggish.

PALIS SILVER 1	1	9.5	6.5	650-810	-	-
	Same as Silver 2 with Lesser Silver.
