SOLDERS

NEW PRODUCT!!

 

NASCO Tin Silver Copper Alloys

 

As from June 2006 European & American Markets are no longer using LEAD Products for the electronic and Electrical Markets. In Keeping with the demand and technology National Solder Co has Manufactured LEAD FREE SOLDER Containing Silver. Tin silver copper alloy can be obtained in wire, sticks and ingots. Tin silver copper wire can be obtained in 0.71mm and 0.9mm and no additional flux is required, as it has resin flux in it. It's applications are similar to NASCO Resin Cored Solders.

 

Technical Data can be found on the technical page or by making a call to National Solder CO.

 

 

 

NASCO Resin Cored Solders

NASCO Resin Cored Solders have excellent "Wetting" properties. This solder is triple cored to ensure even distribution on the work surface. The flux within the triple core is non‑corrosive and non‑conductive. It is ideally suited for all electronic and electrical work. NASCO Resin Cored Solders are manufactured from the purest virgin base metals, highest quality natural resins and small quantities of highly effective activators

Typical applications of NASCO Resin Cored Solders

 

NASCO 63T and 60T Resin Cored Solders are typically used for: electrical, electronic, and other assemblies and components that must not be overheated or that require a free‑running solder. Radio, telephone, instrument assemblies, printed circuits and miniaturization work. Machine soldering of can‑end seams and protective coatings

 

NASCO 50T Resin Cored Solder is generally used for the same applications as the 40T solders.

 

NASCO 40T Resin Cored Solder is typically used for Copper‑bit soldering of electrical, electronic, and general work that is not particularly susceptible to heat damage and that does not require optimum penetration. Batteries, sweated joints in iron and steel (plain, tinned and galvanized), copper, copper alloys, general machine soldering, as well as for the manufacture of electric lamps.

 

All the above NASCO Resin Cored Solders are available on reel sizes of.

  • 3kg (packed 4 per carton)

  • 500g and 250g (packed 20 per carton)

  • Wire diameters (ex-stock) are 3.15mm, 2.50mm, 2.25mm, 2.00mm, 1.60mm, 1.25mm, 0.90mm and 0.71mm.

  • NASCO 40T is also available in 15g household packs (packed 100 per carton).

Please note that other grades and diameters can be made on request by the customer. (Back to Top)

 

 

NASCO Acid Cored Solders

 

NASCO Acid Cored Solders have excellent "wetting" properties with an extremely fast cleaning action.

 

Typical applications of NASCO Acid Cored Solders

 

NASCO 40S Acid Cored Solder is typically used for: general metal work, assemblies that require a free‑running solder, electric lamp manufacture and radiator manufacture.

 

NASCO 30S Acid Cored Solder is typically used for: plumbing, electric lamp manufacture, car body filling and general metal work.

 

Both the above NASCO Acid Cored Solders are available on reel sizes of

  • 3kg (packed 4 per carton)

  • 500g and 250g (packed 20 per carton)

  • NASCO 30S is available in a 15g household pack (packed 100 per carton).

  • Wire diameters (ex stock) are 4.50mm, 3.15mm, 2.50mm, 2.00mm, and 1.60mm.

Please note that other grades and diameters can be made on request by the customer.  (Back to Top)

SOFT SOLDERS

Available in wire, stick, bar or ingot form and can be used for the following applications:

NASCO SABS S1

Commutator as well as fine jointing work and where a component is at risk from heat damage (see melting range under "technical").

 

NASCO SABS S2

Hand soldering of long seam work.  (Unsuitable for zinc or galvanized articles)

 

NASCO SABS S3

Any general work. (Unsuitable for zinc or galvanized articles)

 

NASCO SABS S4 

A non‑antimonial solder which may be used for the soldering of electrical joints. Also suitable for soldering zinc, zinc plated, galvanized and cadmium plated metals. It may also be applied by machine soldering.

 

NASCO SABS S5 

Wiped joints, as plumbers' solder, as well as being suitable for the jointing of lead cable sheathing and other applications where a pasty range is required.

 

NASCO SABS S6 

Hand soldering of long seam work (similar to NASCO SABS S2 but is more suitable for the soldering of brass and galvanized steel).

 

NASCO SABS S7

This soft solder has similar applications to that of NASCO SABS S5. Primarily used for radiator repairs and for applications where a higher tin content is preferred.

 

NASCO SABS S8 

A suitable substitute for NASCO SABS S1.

Used in wave soldering machines for the manufacture of printed circuit boards. Also used in the assembly of stained glass work.

 

NASCO SABS S9
