You've seen it at the trade shows and car shows! You've seen it advertised on TV! You've even seen them solder those holes in the bottom of your favorite Beer Can! . . .
That silver rod that they use is probably our material. If your looking for a few pounds or a few tons, we can supply it. We are the original manufacturers and Our's is the one that went to the moon on the NASA lunar modual. Nobody else can make that claim!
Working with Ney 380
Thank you for your interest in Ney quality alloys and products.
For many years industry has been faced with the difficult problem of effectively and easily soldering aluminum and its alloys. Most products offered for this function on the market today have been found lacking. Either the working temperatures are too high or the strength of the bond is inadequate. This has resulted in disappointment and a certain amount of rejection towards the whole idea of soldering aluminum.
We have overcome most of this with NEY 380, a fluxless aluminum solder that fully meets the requirements of today's industry. This unique product has gained wide acceptance over the last several decades by a broad cross-section of the metals fabrication field. Ney 380 has proven its long awaited and essential integrity that's required by its users through extensive technical research and development combined with independent testing and evaluation. These tests have been carried out on both a national and international level under a wide range of conditions with much acclaimed success.
Fabricators of all types of aluminum have been quick to recognize the unique advantages of NEY 380 and to standardize on its use in production. Repair and maintenance men have included NEY 380 in their inventory of joining materials. Handymen and home-owners have found NEY 380 invaluable both as a repair material and for new work.
Easy to apply . . . No special equipment or skills are needed to produce bonds that exceed the strength of the materials joined. It has enabled methods men, designers, engineers and all who seek better ways of doing things to re-evaluate methods and procedures which had long been shelved.
WHY A FLUXLESS SOLDER ?
Aluminum is coated with a very tenacious oxide which must always be penetrated before a solder joint may be successfully completed. In order to effectively solder aluminum, it is necessary to remove the oxide layer and deposit the solder on the metal itself prior to the reformation of the oxide. Most conventional methods require the use of fluxes. The flux, which is capable of removing the oxide, is also capable of continuing to corrode the joint long after. There is no simple way of removing that flux completely afterwards and thus the need for a fluxless solder becomes evident.
HOW THE BOND IS FORMED
NEY 380 has been especially developed in such a way that by gentle mechanical action, the aluminum oxide layer is lifted and simultaneously a layer of solder is deposited in the joint area. To accomplish this, it is necessary to heat the parts to be joined or the area to be repaired
to a temperature of 716F (380C). This is one of the critical ingredients needed to produce consistently strong, durable joints.
For the majority of applications, either a Gas, Gas air or oxy-acetylene torch is recommended. In the case of the latter the tip size to be used will depend upon the thickness of the aluminum. For very thin parts the heat should be applied and removed quickly to avoid over-heating. On thick material more heat for a longer period of time is required.
When using a gas-oxygen torch, welding and brazing flames should be avoided. The mixture is best when Gas rich with a long cone and long flame feather (reducing flame). It is also possible to use induction and resistance methods, furnaces and dipping.
It is essential that those who work with NEY 380, follow a few fundamental rules. The application technique is critical to its success. There is nothing magical about using the Ney 380 solder, but it does require a bit of patience to mastering this technique. Rule # 1 - Heat the AREA to be soldered and allow the heat from the aluminum to melt the solder. Rule # 2 - The flame must not come in contact with the solder until after the area is tinned.
PLEASE FOLLOW THE DIRECTIONS CAREFULLY !
1. Where anodized or other protective surfaces are involved (other than zinc coatings), remove the protective finish in the joint area. Mill stock finishes do not require cleaning or any other special treatment. Cleaning can be accomplished by bead blasting, sanding, wire brushing, or solvents (no flux). The area should be clear of foreign materials and dirt if possible.
2. The aluminum pieces to be soldered should be held in position by some mechanical means with sufficient firmness to resist the light wiping action of the solder in the joint area. If available, the piece should be placed on a piece of transite board or other non-heat conductive material.
3. The torch flame should be Gas rich with a long cone and feather. Heat should be evenly applied in order to achieve uniform deposits of solder.
4. The proper temperature of 716F (380C) is indicated when a pale orange glow appears at the flames tip. This is the time to remove the flame and very quickly abrade the tip of the rod to the area. The vigorous rubbing motion will yield a slick, shiny film on the aluminum. This film indicates the proper temperature has been reached and the aluminum is being "tinned". If the film does not appear, just apply more heat and abrade the area again. Continue this alternating motion of heat then rod, heat then rod until the entire area to be soldered is covered with the film.
5. Now that the area is tinned, you may apply the flame directly to the rod and allow it to melt into the area. You can use the rod to build up the joint and a brief re-heating of the area will smooth it off if a clean look is desired. For best results the filler should be allowed to cool without quenching. Special Note: Remember that the rod should not be melted by the torch flame until the area is tinned. The heat conducted through the aluminum itself should melt the rod. In a short while a fluxless repair becomes easy with some patience and practice. We suggest that you practice on some discarded aluminum before working on the actual piece.
1. In the service and repair of zinc base alloy dies.
2. May also be used in the bonding of grilles, fuel
pumps, and other similar die cast parts.
3 Effective as a fluxless solder on galvanized surfaces. Provides joints which are stronger than those obtained through conventional soft solder methods.
4. As a fluxless solder for titanium. In this application the titanium is heated to the point where NEY380, when applied to the surface, will form a molten pool. This is followed by abrasion through the pool using a suitable wire brush. This procedure will remove the surface oxide and result in a tinned surface. Following this, the solder may be built up to the desired thickness since the pretinned surface provides a receptive base.
5. NEY 380 may be used in joining dissimilar metals, such as aluminum to copper or stainless steel. This will however involve the use of NEY 380 SOLDERING FLUX.
