Material Group 23.1

  • Al-Mg-Si alloys

Material Group 23.1 ISO 15608 such as EN AW-6061:
Heat treatable aluminium-magnesium–silicon alloys.

EN AW-6061 is a typical alloy in this Al-Mg-Si alloy material group. Generally Al-Mg-Si alloys are precipitation-hardened aluminium alloys. They are commonly available in pre-tempered grades such as 6061-T4/T6 with specified yield strength Rp0,2 > 240 MPa (T6).

The most common temper heat treatment (description in EN 515) for 6061 aluminium is:
T4: Naturally aged to a stable condition
T6: Solution heat treated, quenched and artificially aged

Welding of EN AW-6061 alloy.

Welding of The materials are good weldable with the conventional processes (MIG and TIG). When heat treatable aluminium welded, they lose significant amount of their mechanical properties in the heat affected zone (HAZ). If the base metal being welded is in T4 temper, much of the original strength can be recovered after welding by proper post-ageing. If the base metal is welded in the T6- temper, it can be solution heat treated an aged after welding which will restore it to the T6-temper. However, an post weld heat treating an aging may sous additional problems.

EN AW-6061 alloy , the strength of the original T4 or T6 tempers is reduced in the HAZ due the over-heating. Full re-hardening would require a complete solution heat treatment followed by quenching and artificial aging; as result, the welded assembly will most likely be strongly distorted. Partial re-hardening after weldings is possible up to about 40% of the parent strength.
Therefore, it is recommended,

  • to keep the energy input per unit length of weld as small as possible( to reduce width of HAZ)
  • to weld AlMgSi alloys in the T4 temper followed by age hardening of the complete assembly (if possible).

Applications for : Piping and high pressure gas storage cylinders. According to EN 602, the use of the EN AW-6061 material is allowed for the contact with food.

Applications of Al-Mg-Alloys such EN AW-6061 alloy

Al-Mg-Alloy EN AW-6061 is suitable for the manufacture of pressure vessels and piping in accordance with EN 12392 “Aluminum and aluminum alloys – Wrought and cast products – Particular requirements for products for the fabrication of pressure equipment” see table below.

Material Group 23.2

  • Al-Zn-Mg alloys

Material Group 23.2 EN ISO 15608:
Heat treatable aluminium-zinc-magnesium alloys.

7000 series are alloyed with zinc, and can be precipitation hardened to the highest strengths of any aluminium alloys. Most 7000 series alloys include magnesium and copper as well.

Features of EN AW-7020 alloy

EN AW-7020 is a typical alloy (Cu-free) in this Al-Zc-Mg alloy material group. Generally Al-Zc alloys are precipitation-hardened aluminium alloys. They are commonly available in pre-tempered grades such as 7020-T6 with specified yield strength Rp0,2 > 290 MPa (T6).

The most common temper heat treatment (description in EN 515) for 7020 aluminium is:
T4: Naturally aged to a stable condition
T6: Solution heat treated, quenched and artificially aged

EN AW-7020 material is weldable by standard techniques. The alloy exhibits a good recovery of mechanical properties after welding, approaching the original values of the base metal (depending on welding conditions). These properties can be achieved after natural aging for a prolonged period or after an additional artificial aging treatment.

In Al-Zn-Mg alloys(Cu-free) , strength in the heat effect zone (HAZ) is reduce due to the re-solution of the precipitates. In this case, natural or preferred weldable EN AW-7020 offers unique possibilities due to

  • large solid solution range from 350-500°C
  • low quench rate sensitivity
  • significant age-hardening effect at room temperature

The HAZ reaches the original strength after 90 days of natural ageing.

Note: EN AW-7075 materials with copper can only be welded to a limited extent or not at all (risk of hot cracking).

Applications of EN AW-7020 alloy

Typical applications are highly loaded construction parts and hydraulic applications in acc. to EN 1392 “Aluminum and aluminum alloys – Wrought and cast products – Particular requirements for products for the fabrication of pressure equipment” see table below.
According to EN 602, the use of the EN AW-7020 material is NOT allowed the contact with food.

  • Al-Si cast alloys

Material Group 24.1 ISO 15608:
Aluminium-silicon (Al-Si alloy) cast alloys with 5 % < Si ≤ 15 % and Cu ≤ 1 %

Al-Si alloys

Among the different aluminium alloy alloys, the most used is the Aluminium-Silicon
(Al-Si) alloy with Si concentrations in the range of 5 to 15 wt.%. Si increases the fluidity of the molten metal, therefore improving the castability. Increased tensile strength, good corrosion resistance, good weldability as well as machinability are also results of alloying with Si. The addition of Cu gives a better machinability and increases strength at temperature.

Al–Si–7 Mg Castings alloy

Cast Al–Si–Mg alloys have been widely used in industry for the manufacturing of light-weight structures due to the excellent combination of good castability, strength, ductility, and corrosion resistance. The cast Al–Si–Mg alloys can be significantly strengthened after T6 heat treatment, in order to strengthen the cast Al–Si–Mg alloys further, Cu is usually added into the cast Al–Si–Mg–Cu alloys.

The materials are generally easy to weld.

Material Group 26

  • Al-Cu cast alloy

Material Group 26 EN ISO 15608:
Aluminium-cooper cast alloys with 2 % < Cu ≤ 6 %

Aluminium-cooper cast alloys (Al-Cu) cast alloys

These alloys contain about 4% copper and small amounts of other additives that improve castability, including titanium and magnesium. The AlCu cast alloys are prone to hot cracking and are used in different hardening states. Aluminum-copper cast alloys exhibit very poor casting properties and require more careful design of casting molds to obtain a good casting.

Material Group 31

  • Cu-Ag-Fe alloys

Material Group 31 EN ISO 15608:
Copper with Ag ≤ 6 % and Fe ≤ 3 %

Features of COPPER such as CW024A

The chemical industry uses copper for heat exchangers, distillation columns and column plates, cooling systems, electrostatic precipitator plates, pipelines and seals as well as for many other apparatus parts because of its excellent corrosion resistance to many media and its high thermal conductivity.

Weldability of CW024A

The material CW024A has excellent welding characteristics.

Table: Typical material

ISO 15608 groups materials according to their similar properties such as chemical composition, weldability and mechanical properties. However, it can also be used for other applications such as NDE, forming or heat treatments.

Material assigned to a group in ISO/TR 20172 (European Materials), ISO/TR 20173 (American Materials) and ISO/TR 20174 (Japanese Materials) should considered to those groups.

ISO 15608 material groups reduces the number of welding procedure qualifications (WPQR) e.g. ISO 15614-1. One WPQR is required for a single material group, whereby this material group can contain several specific materials (see tables below). For example, A WPQR with a material from subgroup 1.2 includes all materials from the subgroup 1.1

ISO 15608 is included in many codes and standards so that this simplification of welding qualifications can be used there e.g. EN 13445-2, EN 13480-2, AD 2000, PD 5500, EN 1092-2, ISO 9606.

ASME BPVC Section X has a similar group classification (P-number), but cannot be adopted 1:1. The American system similarly classifies materials into groups, however ASME BPVC Sect. IX in QW422 explicitly classifies grades of materials to groups and not on the chemical composition and mechanical properties such as is the case with ISO 15608.
