WORKING CONDITIONS
Inputs that control grade and geometry
A useful recommendation starts with the load, environment and mating system. Include measured data when available and describe field conditions when it is not.
- Pressure, temperature and fluid velocity
- Solids loading, sand and erosive particles
- Corrosion chemistry and binder compatibility
- Magnetic response, runout and mating tolerances
COMMON FAILURE MODES
Diagnose the mechanism before changing material
- Erosive material loss
- Corrosion or binder attack
- Cracking under pressure or impact
- Seal-face wear and dimensional drift
COMPLETE TOOL + CARBIDE
Engineer the interfaces, not only the insert
Assemblies and components
- Nozzles, seats and flow-control inserts
- Bushings, sleeves and bearing components
- Seal rings and wear pads
- Near-net or precision-finished custom components
Custom decisions
- WC-Co, WC-Ni or corrosion-resistant grade review
- Precision geometry and surface requirements
- Mating-fit and assembly interface
- Drawing, sample and material verification plan
Capability note: complete assemblies are evaluated against the drawing, sample, production volume and available technical evidence. No field-life claim is made until a controlled trial is completed.
VERIFIED COMMERCIAL EVIDENCE
Published evidence for custom downhole projects
The evidence below comes from Ruixin's current product catalogue and public certification page. It demonstrates published material and custom-geometry capability; it is not presented as a downhole assembly photograph or a customer performance case.
Representative custom carbide geometries
Ruixin studio product photograph of carbide preforms and custom shapes. Representative manufacturing evidence only; not a customer installation.
Open source product →Published material systems
WC-Co is the standard system; WC-Ni, WC-NiCr, WC-Co-Cr and selected TiC- or TaC-added systems are published as custom options.
View material range →Published material range
Standard cobalt content 6–20%, grain size 0.4–8.5 μm and hardness HRA 85.5–93.5. Final chemistry is confirmed against pressure, fluid and corrosion requirements.
View published specification →Prototype and delivery scope
Published R&D batches start at 1–5 kg. A first-time formulation is listed at 3–6 weeks; repeat production of an established grade is listed at 2–3 weeks.
View order terms →Inspection documentation
HRA, density, grain structure and optional XRD are listed as project-level qualification outputs. Management-system certificates are publicly displayed on the company page.
View public certificates →Evidence status
Evidence still required: an approved downhole product or assembly photograph, a redacted material/dimensional report, and one traceable anonymous field case. No standard tolerance is claimed for downhole parts until the drawing and inspection method are approved.

Use product pages for grades, dimensions and standard forms
These families are starting points. Final grade, size, tolerance and assembly scope are confirmed from working conditions.

FAQ
Questions engineering teams ask first
When should a nickel-binder carbide be considered?
Nickel-binder or other corrosion-resistant systems may be evaluated when the fluid chemistry can attack cobalt binders. Pressure, temperature, media and required mechanical properties must be reviewed together.
Can Ruixin make precision downhole components from drawings?
Drawing-based evaluation is available for custom components. Critical dimensions, tolerances, surface finish, material requirement, inspection scope and annual quantity are reviewed before feasibility is confirmed.
Are non-magnetic grades available?
Magnetic requirements can be discussed for suitable carbide systems. The required magnetic limits and verification method must be defined in the specification.
