Materials

What we handle.

We evaluate and broker retired high-value alloy-bearing components. We identify the grade, determine the recoverable metal content, and route the material to the right downstream processor.

Furnace and radiant tubes

Retired tubes from industrial heating and processing environments.

  • Furnace tubes
  • Radiant tubes
Recovered: Ni · Cr

High-temperature cast alloy components

Structural and process components exposed to extreme heat.

  • Hangers, supports, rollers
  • Headers, pigtails, catalyst tubes
  • Outlet manifolds, radiant coils
  • Ethylene cracker tubes

Nickel-bearing alloys

Corrosion- and heat-resistant industrial alloys.

  • Nickel-chromium family
  • Nickel-chromium-iron family
  • Nickel-molybdenum family
Recovered: Ni · Cr · Mo

Stainless steels

Standard and specialized corrosion-resistant grades.

  • Austenitic 304, 316, 310, 321

Superalloys

High-performance alloys for extreme mechanical stress.

  • Nickel-based
  • Cobalt-based
Recovered: Ni · Co · Mo · W

Specialty process components

Custom or specific-use industrial components containing recoverable metals.

  • Copper-bearing components
  • Mixed specialty alloys
Recovered: Cu · Ni
Recovered metals

Target elements.

Value is determined by the specific metal content verified in the material.

The seven metals Allovar recovers, where each is found and why it matters
Element Found in Why it matters
Nickel (Ni) Cast tubes, superalloys, nickel alloys, stainless steels With chromium, most of the value in a cast tube. About a third of an HP-modified tube by weight.
Chromium (Cr) Cast tubes, stainless steels, nickel alloys A quarter of an HP-modified tube by weight.
Molybdenum (Mo) Superalloys, nickel alloys The value driver in nickel-molybdenum alloys and many superalloys.
Cobalt (Co) Cobalt-based superalloys The base of cobalt superalloys.
Niobium (Nb) HP-modified and HP-Nb reformer tubes About 1.5 % of an HP-modified tube. It holds the alloy together at temperature.
Tungsten (W) Some superalloys Present in some nickel and cobalt superalloys.
Copper (Cu) Specialty process components Recovered from specialty components.
Questions

Material conditions.

Do you accept small lots?

Send a rough quantity and photos. The evaluation tells you whether the lot can be routed, and to whom.

What if refractory lining or catalyst is still attached?

Say so in the request. Evaluation and logistics are planned around lining or catalyst that is still attached.

Do you handle cutting on site?

Cutting and sizing where needed is part of the logistics step. We arrange it before transport.

What if the grades are mixed or unknown?

We perform XRF analysis on site or on provided samples. This identifies the exact grade and metal content, allowing us to sort mixed lots and route them to the correct buyers.

Have material to evaluate?

Send a description, a location and photos to start.
