Choosing the right aluminum welding wire comes down to the base alloy, the application, and — for automated lines — feed consistency. Below, the three core GOLDING grades compared, plus a quick pick-by-application guide. All grades are supplied on 7 kg precision layer-wound spools, engineered toward a ±0.01 mm diameter tolerance, and ISO 9001 / CE / REACH certified.選對鋁焊線,取決於母材合金、應用場景,以及(自動化產線最關鍵的)送線一致性。以下比較 GOLDING 三大核心型號,並附「依應用快速選型」指南。全系列以 7kg 精密層繞線盤供應,以 ±0.01mm 線徑公差為精度目標,並通過 ISO 9001 / CE / REACH 認證。
| Wire型號 | Alloy Family合金系列 | Best For最適用於 | Automated MIG Notes自動化 MIG 建議 |
|---|---|---|---|
| ER4043 | Al-Si (5% silicon)鋁矽 (5% 矽) | General purpose, automotive, castings, 6xxx base metals — smooth bead, crack-resistant.通用、汽車、鑄件、6xxx 母材;焊道平滑、抗裂。 | Softer wire, low spatter — excellent feedability for high-speed robotic MIG.線材較軟、噴濺低,高速機器人 MIG 送線極順。 |
| ER5356 | Al-Mg (5% magnesium)鋁鎂 (5% 鎂) | Structural, marine, trailers, high strength, anodize colour match — the most-used 5xxx grade.結構件、船用、拖車、高強度、陽極配色;最常用 5xxx。 | Stiffer wire that feeds reliably on push-pull and robotic systems.線材較硬,在推拉式與機器人系統送線穩定。 |
| ER5183 | Al-Mg (higher Mg)鋁鎂 (高鎂) | Shipbuilding, offshore, pressure vessels — highest-strength 5xxx welds, saltwater corrosion resistance.船舶、海工、壓力容器;5xxx 最高強度焊縫、耐鹽水腐蝕。 | Marine-grade strength with a tight ±0.01 mm diameter target for clean, traceable welds.船用級強度,±0.01mm 線徑目標,焊縫潔淨、可追溯。 |
