P0610
High-purity primary aluminum for applications demanding minimal traces and ultra-controlled composition.
P0610 is a primary aluminum grade with purity above 99.80%, used when trace requirements are stricter than P1020. It is used as a base for special alloys requiring extremely low levels of residual elements.

Compared to Similar Alloys
P0610 vs P0404 (Al99.90)
Both are 1xxx-series primary aluminum that we commercialize (not manufacture) as clean remelt charge stock, not as engineering alloys: neither is heat-treatable, and both are soft and highly conductive. The decisive difference is purity grade: P0404 is ≥99.90% Al with lower traces (Fe ≤0.04%, Si ≤0.04%, Cu ≤0.01%), one step above P0610 (≥99.80% Al, Fe ≤0.10%, Si ≤0.06%, Cu ≤0.005%).
| Dimension | P0610 | P0404 (Al99.90) |
|---|---|---|
| Purity grade (Al) | ≥99.80% — high purity, one step below P0404 | ≥99.90% — the highest-purity grade in our primary line |
| Iron and silicon (critical traces) | Fe ≤0.10%, Si ≤0.06% | Fe ≤0.04%, Si ≤0.04% — notably lower traces |
| Copper and residuals | Cu ≤0.005%, others (total) ≤0.10% | Cu ≤0.01%; additional control of Mn, Zn, Ti, V, Ga ≤0.01–0.03% each |
| Heat treatment and strength | Not heat-treatable; soft (UTS 60–70 MPa, ~15 HB, elongation 45–55%) | Not heat-treatable; remelt charge (no published mechanical values; properties as annealed pure metal) |
| Electrical conductivity | ~63% IACS | ~62% IACS |
| Typical application | Base for ultra-low-iron A356.2, aerospace alloys and safety-critical parts; high-purity conductors | Highest-purity base charge for very-low-iron A356.2 (Fe ≤0.12%) and other high-purity alloys; maximum-conductivity conductors |
| Designation / standard | P0610 (AA); High Grade (LME); equivalent ≥99.80% Al | P0404 (AA/ANSI H35.1); Al99.90 (EN 576); comparable to EN AW-1090 / ISO 209 Al99.90 |
P0610: Choose P0610 when you need high purity (≥99.80%) above P1020 at a more accessible tier than P0404, sufficient for premium low-iron A356.2 and high-purity conductors.
P0404 (Al99.90): Choose P0404 (Al99.90) when you need the cleanest possible charge — Fe and Si ≤0.04% — to produce very-low-iron A356.2 or maximum-purity alloys where P0610 does not meet the trace limits.

Frequently Asked Questions
What is P0610 and what is it used for?
P0610 is a high-purity primary aluminum with an aluminum content of ≥99.80% (1xxx series). It is used when trace requirements are stricter than those of P1020, mainly as a premium base for producing ultra-low-iron casting alloys (premium A356.2) and aerospace alloys or safety-critical parts. It is also used in high-purity conductors and specialized electronic components.
What is the chemical composition of P0610?
P0610 guarantees aluminum ≥99.80%, with iron (Fe) ≤0.10%, silicon (Si) ≤0.06%, copper (Cu) ≤0.005%, and total other elements ≤0.10%. The extremely low iron and silicon levels are what distinguish this grade and make it suitable for alloys that cannot tolerate residual traces.
Why is the low iron and silicon content important in P0610?
In aluminum alloys, iron forms intermetallic phases that reduce ductility and mechanical performance, so starting from a base with Fe ≤0.10% allows meeting ultra-low-iron specifications such as those of premium A356.2. In addition, the low impurity level gives P0610 the maximum thermal conductivity (235 W/m·K) and electrical conductivity (63% IACS) among commercial aluminums.
How does P0610 differ from P1020?
Both are primary aluminum of the 1xxx series, but P0610 has higher purity (≥99.80% Al) and is commercialized precisely when P1020 does not meet the customer's purity requirements. P0610 is the right choice when ultra-low-iron specifications or the maximum possible electrical conductivity are needed.
Is P0610 heat-treatable or hardenable by heat treatment?
No. As a 1xxx-series primary aluminum, P0610 is not heat-treatable; it lacks the alloying elements needed for precipitation hardening, so it is not supplied in tempers such as T5 or T6. It is an essentially pure, soft material (hardness ~15 HB, tensile strength 60–70 MPa) with very high elongation (45–55%); its value lies in its purity, not in mechanical strength.
Does TP make P0610 from primary stock or from recycled wheel scrap?
P0610 is a high-purity primary aluminum grade, so it must start from primary stock; purity levels of ≥99.80% with iron ≤0.10% are not achievable from recycled wheel (rin) scrap, which is A356.2 casting metal with higher traces. At TP we commercialize P0610 as a premium base for producing alloys with ultra-low-iron specifications or when the customer requires maximum conductivity.
