It also contains magnesium, which gives it better response to heat treatment and improved strength compared to binary Al-Si alloys. The alloy is supplied primarily as wire, rod, coil and sheet for welding, brazing and heat-transfer applications. It offers good fluidity, corrosion resistance and electrical\/thermal conductivity, but it is not chosen for high-strength structural parts. Linsy Aluminum supplies 4005 in standard tempers and custom dimensions to meet project specifications.<\/p>\n<h2>Available 4005 Aluminum Products<\/h2>\n<p>Linsy stocks and produces 4005 aluminum in the following forms. Cut-to-length, custom diameter and specific coil weights are available on request.<\/p>\n<h3>4005 Aluminum Wire &amp; Rod<\/h3>\n<p>4005 wire and rod are the most common forms. They are used as filler metal for TIG\/MIG welding and as brazing rod. Diameters typically range from 0.8 mm to 6.0 mm for wire and 6 mm to 50 mm for rod. Other sizes are available on request.<\/p>\n<table>\n<tr>\n<th>\uc81c\ud488<\/th>\n<th>\uc9c0\ub984(mm)<\/th>\n<th>Common Temper<\/th>\n<th>\ud3ec\uc7a5<\/th>\n<\/tr>\n<tr>\n<td>4005 \uc54c\ub8e8\ubbf8\ub284 \uc640\uc774\uc5b4<\/td>\n<td>0.8 \u2013 6.0<\/td>\n<td>O, H14, H18<\/td>\n<td>Spool \/ Coil<\/td>\n<\/tr>\n<tr>\n<td>4005 Aluminum Rod<\/td>\n<td>6.0 \u2013 50<\/td>\n<td>O, H14, H16<\/td>\n<td>Straight length \/ Coil<\/td>\n<\/tr>\n<\/table>\n<h3>4005 Aluminum Coil &amp; Strip<\/h3>\n<p>Coil and strip are supplied in annealed or half-hard tempers for brazing sheet and heat exchanger fin stock.

It wets steel and aluminum joints well, produces low crack sensitivity, and is suitable for TIG, MIG and furnace brazing when matched with compatible base metals.<\/p>\n<h3>Corrosion and Oxidation Resistance<\/h3>\n<p>The alloy offers good resistance to atmospheric and mild chemical corrosion. A light oxide layer forms naturally; surface cleaning or pickling may be required before welding or brazing to avoid porosity.<\/p>\n<h3>Formability and Electrical Conductivity<\/h3>\n<p>In the annealed condition, 4005 is easy to form and bend. Its electrical and thermal conductivity are lower than pure aluminum but still suitable for many heat-transfer and electrical joint applications.<\/p>\n<h2>\uc77c\ubc18\uc801\uc778 \uc560\ud50c\ub9ac\ucf00\uc774\uc158<\/h2>\n<ul>\n<li>Welding and brazing filler wire and rod<\/li>\n<li>Heat exchanger tubes, fins and headers<\/li>\n<li>Automotive HVAC and condenser assemblies<\/li>\n<li>Electrical and grounding conductors<\/li>\n<li>Architectural and decorative brazed components<\/li>\n<li>General industrial joining materials<\/li>\n<\/ul>\n<h2>Processing &amp; Surface Finish Notes<\/h2>\n<p>Linsy can support the following processing for 4005 products:<\/p>\n<ul>\n<li><strong>Cutting to length:<\/strong> Wire, rod and sheet cut to your specified length or coil weight.<\/li>\n<li><strong>Straightening:<\/strong> Rod and wire supplied on coils or in straightened lengths.<\/li>\n<li><strong>Annealing:<\/strong> Available to restore ductility after forming.<\/li>\n<li><strong>Surface cleaning:<\/strong> Degreasing, pickling and light polishing to prepare for welding or brazing.<\/li>\n<li><strong>\ud3ec\uc7a5:<\/strong> Spools, drums, coils and wooden crates for protection during shipping.<\/li>\n<\/ul>\n<p>4005 is not ideal for anodizing because the high silicon content can produce dark or uneven finishes.
