2007 aluminum alloy (UNS A92007) is a copper-based 2xxx series aluminum alloy designed specifically for high-speed free-machining applications. The alloy is alloyed with copper (3.3–4.6%), magnesium (0.4–1.8%), lead (0.8–1.5%), and bismuth — the lead and bismuth additions form dispersed particles that promote chip breakage during cutting, resulting in short, brittle chips and excellent surface finish at high machining speeds.
2007 is recognized as one of the fastest-machining aluminum alloys available, comparable to 2011 (AlCu6BiPb) and 6026 (AlMgSiBi) in terms of machinability. Its chip-breaking characteristics make it particularly well-suited for precision threading, turned parts, and high-volume automatic lathe production. However, due to its high copper content, 2007 has poor corrosion resistance, low weldability, and is generally not recommended for structural or welded applications. It is also classified as unweldable by conventional arc welding methods.
The alloy is covered under EN 573-3 as EN AW-2007/AlCu4PbMg, and is primarily supplied in bar, round bar, rod, and wire forms for the machining industry.
Linsy supplies 2007 aluminum alloy in common machining stock forms. Length, diameter, and dimensional tolerances can be customized to your production requirements.

2007 aluminum alloy is primarily used in machining applications. The table below summarizes the key characteristics and best-use cases for the most commonly supplied tempers.

| T4 | Solution heat-treated, naturally aged. Lower strength than T3, better ductility. | Parts requiring cold forming before machining, rivets |
| O | Annealed, softest condition. High ductility, low strength. | Forming operations before machining, cold heading |
2007 is one of the fastest-machining aluminum alloys. The combination of lead and bismuth particles promotes chip breakage at high cutting speeds, producing short, brittle chips that clear easily from the cutting zone. This results in consistent surface finish, reduced tool wear, and high productivity in automatic lathe and CNC turning operations.
With its fine and consistent chip formation, 2007 delivers clean, accurate threads in single-point threading, tapping, and thread rolling operations. It is a preferred material for high-volume production of threaded fasteners, bolts, nuts, and precision adjustment screws.
Due to its high copper content (3.3–4.6%), 2007 aluminum has relatively low corrosion resistance compared to 5xxx and 6xxx series alloys. Components made from 2007 may require protective coatings, anodizing, or plating in corrosive or outdoor environments.
2007 aluminum alloy is considered unweldable by conventional arc welding methods (TIG/MIG). The high copper content promotes hot cracking and significantly weakens the heat-affected zone. Mechanical fastening and adhesive bonding are recommended joining methods for 2007 components.
2007 aluminum alloy is widely used in industries where high-speed precision machining and thread quality are critical. The table below outlines common application areas.
| Setor | Aplicações típicas | Why 2007 Is Used |
|---|---|---|
| Engenharia de Precisão | Turned parts, bushings, spacers, couplings | Short-chip machining, excellent surface finish |
| Fastener Manufacturing | Bolts, nuts, screws, rivets, threaded inserts | Clean thread formation, high-speed production |
| Automotivo | Fuel system fittings, sensor housings, valve components | Consistent machinability in high-volume production |
| Watch & Instrument | Watch cases, clock parts, precision adjustment mechanisms | Fine surface finish, dimensional stability |
| Eletrônicos | Connector bodies, heat sinks, encoder wheels | Good thermal conductivity for a machining alloy |
| General Manufacturing | Prototype parts, jigs, fixtures, custom machined components | Fast turnaround, low cost-per-part in machining |
2007 alloy excels in CNC turning, milling, drilling, and tapping operations. It can be machined at higher speeds than 6061 or 7075, with cycle-time reductions of 30–50% achievable at equivalent surface finish quality. Carbide or high-speed steel tooling performs well, and neat cutting oil or flood coolant may be used depending on the machine setup and production volume.
Single-point threading, thread milling, tapping, and thread rolling all produce clean results in 2007. The alloy’s chip-breaking characteristics virtually eliminate the risk of stringy-chip buildup — a common issue when threading 6061 or 5052 aluminum.
2007 can be polished to a bright finish for decorative and instrument applications. Anodizing produces a protective layer, though 2007 (2xxx series) anodized films tend to have a yellowish or greyish tone and are less clear than those on 5xxx or 6xxx series alloys. For applications requiring strong corrosion protection after anodizing, hard anodizing or chemical conversion coatings should be considered.
2007 is classified as unweldable by conventional TIG and MIG processes due to its high copper and lead content. Attempting to weld this alloy typically results in hot cracking, porosity, and severe strength loss in the heat-affected zone. For applications requiring joining, use mechanical fasteners, press-fits, or adhesive bonding instead.
Every order of 2007 aluminum alloy from Linsy includes a Mill Test Certificate (MTC) documenting the heat number, chemical composition, mechanical properties, and dimensional tolerances of the supplied material.

What is 2007 aluminum alloy used for?
2007 aluminum is primarily used for high-speed precision machining applications, including turned parts, threaded fasteners, bolts, nuts, rivets, bushings, watch components, and prototype machined parts. Its lead and bismuth content ensures short-chip formation and excellent surface finish during machining.
Is 2007 aluminum alloy weldable?
No. 2007 is classified as unweldable by TIG, MIG, and other conventional arc welding processes due to its high copper and lead content. Mechanical fastening and adhesive bonding are recommended alternatives.
What is the difference between 2007-T3 and 2007-T451?
Both are solution heat-treated, cold-worked, and naturally aged conditions. T451 includes an additional stress-relief step by stretching, which reduces internal residual stress and improves dimensional stability during machining — making it the preferred temper for precision parts.
How does 2007 compare to 2011 aluminum?
Both 2007 (AlCu4PbMg) and 2011 (AlCu6BiPb) are high-speed free-machining 2xxx series alloys. 2011 contains higher copper (~5.0–6.0%) and is often considered the fastest-machining aluminum alloy. 2007 offers better overall mechanical properties and is preferred where a balance of machinability and strength is required.
Can 2007 aluminum be anodized?
Yes, but the anodized appearance will differ from 6xxx series alloys. 2007 anodized films tend to appear yellowish or greyish due to the copper content, and the coating may be less clear than what you would get with 6061 or 5052. Hard anodizing or chemical conversion coatings may be preferred for corrosion protection.
Why does 2007 aluminum contain lead?
Lead is intentionally added (0.8–1.5%) to improve machinability. Lead particles are insoluble in the aluminum matrix and act as chip breakers during cutting, producing short, brittle chips that clear easily and reduce tool wear. This is the primary reason 2007 achieves such high-speed machining performance.
