Bonded Premixes

A powder-metallurgy premix route built around the base powder, lubricant and additive system, compaction conditions and sintered-part target. The route is confirmed in the current Luyin product range; formula and performance values remain controlled until a current TDS and review basis are supplied.

Define the mix architecture before asking for a grade.

A useful review starts with the current formulation or the performance gap. Luyin can then confirm whether the requested route is within current supply scope and which controlled documents are available.

  • Base powder system
  • Lubricant / additive
  • Compaction route
  • Sintered-part target
Selection viewOne route. Two ways to prepare the review.
Structural PM PartsProvide the part material, pressing route, green-density target, sintering conditions and required mechanical result.
  • Technical match required
Current Premix ReplacementProvide the current supplier grade or TDS, recent COA, addition system and the problem the replacement must solve.
  • Comparable evidence required
New Formula DevelopmentDefine the base powder, additive constraints, compaction and sintering window, evaluation method and trial volume.
  • Supply review required

No premix grade, formula ratio or performance value is presented as current supply data on this local page. Those items require a controlled Luyin document and current supply confirmation.

This is a qualification-route matrix, not a technical specification. Formula values and batch guarantees are intentionally absent.

Define the formulation before specifying the premix.

The illustrated base-powder choices are water-atomized pure iron, water-atomized pre-alloyed steel and diffusion-alloyed steel. Nickel, carbon and copper are examples of additions, not a universal recipe.

Agree the base grade, composition, lubricant, pressing conditions and evaluation targets. Actual batch results are provided in the COA.

Follow the complete premix production route

From base powder to bonded premix.

The diagram shows the alternative base powders, formulation additions, bonding, lubricant addition and final mixing as separate steps.

Evidence before formula commitment.

Purchasing and engineering receive the same controlled route status. A public family name never substitutes for a current formulation, release method or batch document.
