Aluminum solderUses: Used for aluminum wire, aluminum wire, aluminum wire and copper; welding aluminum wire with iron and stainless steel.

Scope of application for aluminum flux: Suitable for the production of high and low voltage transformers, distribution boxes, lighting distribution boxes, high-power voltage regulators, high-precision automatic voltage regulators, various models of isolation transformers, and motors.

Usage method of aluminum solder: First clean the welding surface, then apply aluminum solder before welding.

Precautions for aluminum solder: 1. After welding, if there are residues, they can be wiped with a wet wipe. 2. The welding temperature is 3305 degrees. Performance: flame retardant, non-toxic, non-corrosive wax.

Industries using aluminum solder:

　　Aluminum solderIt is a viscous liquid; what is its main function? How much do you know about its scope of use? First, let's introduce the general scope of use for aluminum flux.

Aluminum solder is a basic flux for welding aluminum and aluminum alloys with lead-tin based solder, as well as for welding aluminum with copper, steel, copper alloys, and other metals. It can be used in the electronics industry for welding aluminum enameled wire, aluminum plates, and aluminum lamp holders. Its main function is to remove the oxide film on the metal surface and increase the wettability of the solder on the metal surface, allowing the solder to bond with the metal substrate.

The wettability and bonding strength between the solder and aluminum are related to the composition of the solder and the silicon and magnesium content in the aluminum. Zinc can enhance the wettability of the solder on the aluminum surface. However, it is difficult to weld high magnesium and silicon content aluminum alloys using lead-tin solder.

Classification of aluminum solder:

Different types of aluminum flux have different functions when used, mainly depending on the type of aluminum flux. Then, based on type, aluminum flux can be divided into several categories. What are the differences? Let's briefly introduce the classification of aluminum flux.

There are many types of aluminum solder with various functions; they can be divided into five major categories based on the functions and roles of additives, such as crosslinking agents and process additives.

　　Aluminum solderCan be divided into:

1. Optimize processing performance: lubricants, release agents, stabilizers, processing aids, thixotropic agents, etc.

2. Optimize mechanical properties: plasticizers, reinforcing fillers, toughening agents, impact modifiers.

3. Optimize optical properties: pigments, dyes, nucleating agents, and fluorescent whitening agents.

Usage of aluminum solder:

Before introducing usage methods, let's talk about the classification of fluxes. They can be divided into a series of non-polar fluxes known in the market as 'solder oil'. Care should be taken to clean after use; otherwise it may cause corrosion and damage to welded objects. Another type is organic series fluxes that decompose quickly and leave inactive residues. Another type is resin active series fluxes that are non-corrosive, highly insulating, and stable over time. Commonly used fluxes are rosin-based fluxes with active agents.

Generally speaking, using aluminum solder is relatively simple. First wipe off any oil stains from the workpiece with alcohol; then apply the flux to the surface to be welded before welding. However, it is essential to clean thoroughly after welding; safety precautions should be observed to avoid contact with nose, mouth, throat or skin. When not in use, seal it well and store it in a cool and ventilated place.
