Electro Metals Solders

With the increasing requirements for hot air leveled, solder coatings on PC boards (PC Board Solder), the demands on the quality of the solder used have to increase dramatically – we can meet these stringent requirements.

Physical properties of Solders

	COMPOSITION, PHYSICAL PROPERTIES AND APPLICATIONS
SOLDER		COMPOSITION (Wt. %)				PHYSICAL PROPERTIES					APPLICATIONS
ALLOY CLASSIFICATION		Tin	Lead	Antimony	Silver	Tensile	Shear	Density	Temperature (F0)

						lb./sq. in.	lb./sq. in.
									Solid	Liquid
Tin-Lead Solder		5	95	-	-	4000	2100	0.397	581	594	For sealing pre-coated containers, coating and joining metals
Low melt range makes them ideal for joining most metals by convenient heating methods.		10	90	-	-	4400	2400	0.386	514	578	For fabricating auto radiators, and coating and joining metals where service temperatures are low enough to permit their use.

		20	80	-	-	4800	3000	0.363	361	531
		25	75	-	-	4900	3500	0.359	361	511	For auto Radiators and cans when machine or torch soldering.
		30	70	-	-	5000	4000	0.35	361	491
		35	65	-	-	5200	4300	0.343	361	477	Solder for wiping and sweating joints.
		40	60	-	-	5400	4600	0.336	361	460	General purpose solder for sheet metal, radio and TV applications.
		45	55	-	-	5700	4900	0.328	361	441	For radiator cores, TV applications, and roofing seams.
		50	50	-	-	6000	5200	0.321	361	421	General-purpose solder for plumbing and sheet metal work.
		60	40	-	-	7600	5600	0.306	361	374	Commonly used for wave and dip soldering of electronic assemblies where low temperatures are required.
		63	37	-	-	7600	5400	0.301	361	361
Tin-Antimony Solder(Lead-Free)		95	-	5	-	5900	6000	0.26	455	464	Designed for use in electrical or electronic connections subject to peak temperatures of approximately 4000F and in sweating copper tube joints in refrigeration equipment.
Tin-Lead Antimony Solder		20	79	1	-	6300	3400	0.369	369	517	For machine soldering and coating of metals, tipping, and similar uses.  Not recommended for use on galvanized iron.
		25	73.7	1.3	-	6400	3900	0.359	364	504	For torch or machine soldering, except on galvanized iron.
		30	68.4	1.6	-	6500	4520	0.348	364	482
		35	63.2	1.8	-	6600	4700	0.341	365	470	For wiping joints and general application.  Not recommended for use on galvanized iron.
		40	58	2	-	6900	5000	0.333	365	448	General-purpose grade for radiator cores, plumbing, electrical and electronic connections, roofing seams, and heating units. Not recommended for use on galvanized iron.
Silver Solder		1	97.5	-	1.5	4400	3400	0.408	588	588	For sequential soldering where lower melting alloy will be used for second joint.  Used where high service temperatures are encountered (as in food service equipment and radiators).  Also for soldering fine copper wires.
		62	36	-	2	8600	6600	0.307	364	372	For soldering delicate instruments and for use where silver-coated surfaces are to be soldered.
