Flexbar Fixturing Alloy 1 lb Cake - 15158 

FIXTURING ALLOY

• Reusable low-temperature melting Alloy (158 degree F) for supporting thin-walled sections which require machining. No. 15158 does not shrink upon solidification rather it exhibits slight "growth" so that it locks into the part being machined. After machining you simply melt it out in hot water.
• It melts at 54 degrees F below boiling point of water so that when you go to use it you simply put it in a cast iron, stainless steel or porcelain lined pot and into hot water bath to melt it.
• Reusable many times.
• No drosses created owing to low heat required prior to pouring it.

USES OF NO. 15158:

ANCHORING:

• Locator Members in Aircraft & Automotive Assembly, Drill, Inspection & Welding Fixtures.
• Precision Parts for Testing & Inspection.
• Reamers for Axial & Concentric Alignment in Turret Tool Holders.

CHUCKS, JIGS AND FIXTURES:

1. Spinning Metal into Re-Entrant or Bottle Neck Shapes.
2. Holding Irregular Shaped Work Pieces During Machining.
3. Bushings Anchored in Drill Jigs.
4. Cast Ref. Surfaces in Assembly, Checking, Die Spotting, Drilling, Inspection Fixtures.
5. Transfer Templates in Contour Jigs.

DIES AND PUNCHES:

6. Drop Hammer, for Short Run Sheet Metal Forming.
7. Light Sheet Metal Embossing Dies. 

Other Uses:

• Heat Transfer,  Tempering,  Sheet Plastic Curing,  Vulcanizing,  Dyeing
• Tube Bending (replaces other materials such as lead, tar, sand and rosin) which have disadvantages such as: Flammability - difficulty of removal-inadequacy to fill void fully, etc. Plated tubes can be bent-swaged-rolled-or drawn.
• Reveals pin holes or cracks owing to liquidity of No.15158, also thin sections revealed by slight expansion of No. 15158 upon solidification.
• Bending procedures and other data as well as Do's and Dont's included with material.

Instructions for Use:

Material melts at 158°F so that you can heat it in a small pot or ladle either over a burner or in a double boiler (pot in a hot water bath). Pot can be stainless, porcelain lined or cast iron. Aluminum, brass, or copper vessels are not recommended. Thermostatically controlled melting pots are good.

Procedure:

1. The molten alloy is poured into or around the item to be machined. A simple dam or jug to contain the alloy until solidified is all that is required.
2. Although the molten alloy can be solidified more quickly with water or a fan, it is not necessary, but it would produce a finer crystalline structure. As the alloy is used at such a low temperature there is no danger of affecting the temper of the work piece.
3. The part is then machined to the necessary configuration.
4. Removal of the alloy is accomplished in hot water or with a steambath. Chips that float to the top of the molten alloy are removed by skimming, leaving the alloy sufficiently clean to be reused.
