Introduction and use of ER4043 aluminum welding wire

The ER4043 aluminum welding wire is a demanded product from the UAE customer. The required wire diameter is 1.2mm, which is the conventional aluminum wire size. This article introduces the ER4043 aluminum welding wire to the needs of UAE customers.

1.ER4043 aluminum welding wire introduction

ER4043 aluminum alloy has the characteristics of low melting point, good fluidity and good corrosion resistance. It is very beneficial to avoid welding cracks and is specially used as welding material. As a kind of versatile aluminum-silicon welding wire, ER4043 has good resistance to thermal cracking on deposited metal and can also guarantee certain mechanical ability.

2. ER4043 aluminum welding wire performance characteristics

ER4043 is a silicon-containing 5% aluminum-silicon alloy wire, also known as S311. It has good fluidity and is used for welding forged and cast materials because of its weak sensitivity to hot cracks. It is also used as a filling material for argon arc welding and brazing of aluminum alloy workpieces and castings other than aluminum-magnesium alloys. It is easy to form brittle Mg2Si in the weld during welding, which reduces the plasticity and corrosion resistance of the joint, so the wire is generally not used for welding aluminum-magnesium alloy. The welding is beautiful and the sightseeing is bright, the arc is stable, and the splash is small, but the color is different from the base material after the anodizing treatment.

The melting temperature of ER4043 ranges from 1065-1170oF, the color after anodization is off-white, and the low tensile strength is 186MP.

3.The chemical composition of the ER4043 aluminum welding wire is as follows:

Composition (%)	Al	Si	Fe	Cu	Mn	Mg	Zn	Ti
ER4043	92.5-94	4.50-6.00	≤0.80	≤0.30	≤0.05	≤0.05	≤0.10	≤0.20

4. ER4043 aluminum welding wire welding method and use

Welding method of ER4043: AC argon arc welding, pure argon gas protection. It is necessary to clean the workpiece weld before welding, and avoid air, weldment and welding wire damp.

Use of ER4043 aluminum welding wire: used for welding of 6601 series aluminum alloy, 3XXX series and 2XXX series aluminum alloy and cast aluminum. Widely used in ships, locomotives, chemicals, food, sports equipment, molds, furniture, containers, containers.

The above is an introduction to the performance characteristics, chemical composition and use of ER4043 aluminum welding wire. I believe that everyone has a certain understanding of ER4043 aluminum welding wire. It is widely used in our lives and it is also indispensable. At present, the demand for aluminum wire of our company is very large. In terms of products, some manufacturers in the market may have lower prices, but generally there will be some problems in the use process. Our company's aim is to insist on using quality to speak, to provide quality assurance and quality after-sales service.

Why Choose EB Pure Nickel Wire

Why Choose EB Pure Nickel Wire

1. Product Introduction

Nickel wire series products include: nickel wire, pure nickel wire, nickel alloy wire, 0.025mm nickel wire, N4 nickel wire, N6 nickel wire; nickel wire purity can reach 99.99%, the finest can reach 0.025mm.

Status: Hard/semi-hard/soft

2. Pure Nickel Wire Characteristics

Nickel mechanical properties are close to carbon steel.Its alkaline corrosion resistance is second only to silver in metal materials, nickel wire will form a black protective film on the surface of concentrated alkali. Make it very resistant to corrosion. It is mostly used for electric light source materials, coating, with high surface quality and good processing performance. It is used for making work such as anode, separator, electrode holder, etc. It can also be used as guide wire lead in bulb, and it plays an important role in chlor-alkali industry. The role. Electric grade materials have various alloys depending on the conditions of use. Moreover, the electrode materials are required to have a low resistivity to avoid overheating of the electrode, high high temperature strength to reduce material wear, and a relatively viscous melting and volatilization under the action of an arc to improve the service life and the like.

Features:

(1) with solderability, high conductivity, suitable coefficient of linear expansion

(2) the strength is better at high temperature, the resistivity is lower

(3) 3, high melting point, corrosion resistance, good mechanical properties, good pressure processing in hot and cold conditions, easy to degas, suitable for radio, electric light source, machinery manufacturing, chemical industry, is important in vacuum electronic devices Structural materials.

3. Pure Nickel Wire Type:

Pure nickel wire can be divided into N4 and N6 according to the material.

(1) N4 pure nickel wire

That is, N4 nickel wire, also known as nickel No. 4.

N4 nickel wire has good mechanical strength, corrosion resistance and heat resistance. It is suitable for the production of vacuum devices, electronic components, chemical filters for strong alkalis.

N4 pure nickel wire is suitable for radio, electric light source, mechanical manufacturing, chemical industry, and is an important structural material in vacuum electronic devices.

(2) N6 pure nickel wire

N6 pure nickel wire also has good corrosion resistance and excellent corrosion resistance of hot alkali resistant solution.

It has excellent corrosion resistance to alkaline and neutral solution media such as carbonates, nitrates, sulfates, chlorides and acetates

4. Pure Nickel Wire Use

Pure nickel wire is suitable for radio, electric light source, mechanical manufacturing, chemical industry, is an important structural material in vacuum electronic devices, and can also be used as a guide wire lead in the bulb.
