Galvanizing Flux

AMCO 4986

Retards the formation of oxide on the surface of the zinc baths and fluxes the base metal as it passes through the top flux. The zinc coating provides protection to the iron and steel in two ways:

1) The coating shields the base metal from the atmosphere;

2) Because it is more electronegative than iron or steel, the zinc gives sacrificial protection. Even if the surface is scratched and the base metal is exposed, the zinc is slowly consumed while the base metal remains protected from corrosion.

Galvanizing Repair

AMCO 321

A fine, homogenous blend of flux and powdered metal for the repair of galvanized surfaces. Similar to Amco 322, but in powdered form for hard to reach repair areas. Contains 60% metal.

AMCO 322

A blend of inorganic flux with powdered zinc, tin, and lead alloys compressed into 5/8" sq. by 4" long sticks. Used for repair of hot dipped galvanizing surfaces. Forms a metallurgical bond with virgin metal and the galvanized surface. One box contains 3 sticks equaling one pound.

AMCO 3017

A 1/4" square by 14" long bar of tin, zinc and lead designed to deposit a protective metallic coating over ferrous metal. It is suitable for repairing galvanized surfaces damaged by rough handling or welding. For plant and field repair of galvanized surfaces.

Conforms to ASTM A780-93 4.2.1.
New York DOT approved.


AMCO 95/5

Soldering paste containing a zinc chloride base flux and 95/5 tin-lead) powdered alloy. It is used to join tubes and fittings.

AMCO 2151

A single component flux and solder formulation. Consists of zinc chloride based flux and 50/50 tin-lead powdered alloy. Excellent for joining copper based tubes and fittings. May also be used for tinning and joining ferrous metals such as cold rolled steel.

AMCO 3440

a single component flux and solder formulation consisting of zinc chloride based flux and 40/60 tin-lead powdered alloy. It is excellent for joining copper based tubes and fittings. It may also be used for tinning and joining ferrous metals such as cold rolled steel.

AMCO 4570

Smooth homogenous solder in paste form. It is formulated as a single component flux and solder which allows the product to clean metal surface and leave a tin-lead alloy metal coating as it is heated. The product can be used on cold rolled steel and copper based metals. Contains a zinc chloride base with 40/60 tin-lead powdered alloy.

AMCO Paste
