YIRUI Alloy — Magnesium & Aluminum Alloy Casting Manufacturer
YIRUI Alloy is a magnesium and aluminum alloy casting manufacturer founded in 2006 in Jiaozuo, China — producing castings, alloy rods, extruded profiles, and cathodic-protection anodes, with foundry, machining, heat treatment, and inspection in-house.
Products
What YIRUI makes
Magnesium and aluminum alloy products — castings, rods, extruded profiles, and drawing-based components — plus a full cathodic-protection line, all produced from customer drawings, agreed specifications, or recognized standards.

Magnesium Alloy Castings
Structural magnesium castings by low-pressure sand casting and gravity die casting, for parts with cavities and load-bearing features.
Magnesium castings →
Aluminum Alloy Castings
Aluminum castings to GB/T 1173 grades by gravity die and low-pressure casting, machined and heat-treated to drawing.
Aluminum castings →
Magnesium Alloy Rods
Rare-earth magnesium rods by DC semi-continuous casting with controlled melt treatment and T5/T6 aging.
Magnesium rods →
Magnesium & Aluminum Alloy Components
Drawing-based components: cast, machined, heat-treated, and inspected in the same plant.
Alloy components →
Magnesium Extruded Profiles
Custom magnesium sections extruded from in-house DC-cast billet, quoted to your section drawing and batch-tested.
Extruded profiles →
Cathodic Protection
The full corrosion-control line — aluminum, magnesium, ribbon & impressed-current anodes, reference electrodes, and test stations.
Cathodic protection →Capabilities
The route is chosen for the part
Process selection is based on geometry, alloy, and application — four casting routes, extrusion, machining, and heat treatment under one roof.
Investment Casting
CT4–CT6 tolerance, walls down to 0.5 mm, for complex aluminum precision parts.
Low-Pressure Sand Casting
Bottom-up filling for medium-to-large structural parts in magnesium and aluminum systems.
Low-Pressure Magnesium Casting
The low-pressure route applied to structural magnesium parts with cavities and load paths.
Aluminum Alloy Casting
A356, A360, and 355 (GB ZL101/104/105) recommendations with T1/T4/T5/T6 heat treatment.
Gravity Die Casting
Metal-die route for geometries and volumes where it beats sand or investment casting.
Magnesium Rod Casting
DC semi-continuous casting with online refining, degassing, filtration, and stirring.
Extrusion & Ribbon Forming
Profiles and anode ribbon extruded from billet cast in-house.
Capability overview
All processes, downstream operations, and the engineering flow on one page.
How YIRUI Works
An engineering supplier, not a catalog
Most parts start as a customer drawing. The plant is set up to take that drawing through process selection, casting, machining, heat treatment, and inspection without leaving the site.
Made to your drawing
Custom programs are built around your 2D/3D files and specifications, from prototype through production.
The route fits the part
Investment, low-pressure sand, gravity die, and DC rod casting are chosen by geometry, alloy, and application.
Inspected in-house
Composition, internal soundness, mechanical properties, and dimensions are checked with our own equipment.
University R&D behind it
A joint laboratory with Xi’an Jiaotong University since 2017 and a provincial engineering platform support 30+ patents.
Quality
Inspection runs in-house
Composition, mechanical properties, internal soundness, and surface defects are checked with YIRUI’s own equipment under ISO 9001:2015, ISO 14001, ISO 45001, and GJB9001C-2017.



How We Work
From drawing review to final acceptance
Every program follows the same controlled path defined in the quality system, with engineer-to-engineer coordination from prototype to production.
Drawing review
Geometry, alloy, tolerances, and inspection points are reviewed before quoting.
Process planning
Casting route, tooling, and heat-treatment condition are selected for the part.
Process review
Methoding and parameters are checked before any metal is poured.
Trial production
First articles are cast, measured, and tested against the drawing.
Pilot run
A small batch proves repeatability before release to volume.
Mass production
Batch verification with barcode traceability from material to shipment.
