Dissolvable Magnesium Alloy Round Bar

Dissolvable Magnesium Alloy Round Bar – Engineered for Downhole Excellence

When your completion program demands zero retrieval risk and predictable performance, you need more than commodity material. Our Dissolvable Magnesium Alloy Round Bar delivers enterprise-grade consistency with extruded diameters up to Ø300 mm, tensile strength spanning 320–480 MPa, and controlled dissolution rates from 1 to 100+ mg/cm²/h in 3% KCl solutions. Backed by CNAS-accredited HTHP testing, ISO-certified production, and full batch traceability, every rod ships with documented COA/COC/SDS packages. Lead times stay tight: 2–4 weeks for standard specs, 4–8 weeks for custom engineering—so you can validate faster and scale with confidence.

What Makes Our Round Bar Different?

Consistency You Can Machine

Low-density material (approximately 1.8 g/cm³) meets precision extrusion.

Uniform grain structure means fewer tool breakages.

Your CNC department will thank you.

Dissolution on Your Terms

We tune chemistry and heat treatment to match your fluid profile and working window.

Whether you need 24-hour stability or 7-day degradation, we dial it in—no guesswork.

Built for High-Pressure Reality

Our high-strength grades handle differential pressures up to 10,000–15,000 psi in real downhole assemblies.

They hold when they need to.

They dissolve when you want them to.

Traceability That Passes Audits

Every billet ships with a data package: chemistry report, mechanical test results, and dissolution validation.

You get supplier qualification done right the first time.

Technical Specifications

Why International Buyers Partner With Hagrien?

Integrated Manufacturing Control

We don't buy magnesium billets from brokers.

We melt, extrude, and machine under one roof.

That's how we guarantee repeatability—from prototype to production lot 50.

Engineering Support, Not Just Material Supply

Send us your assembly drawing and working conditions.

We'll recommend the right alloy grade, predict dissolution behavior, and help you design machining windows that reduce scrap for Dissolvable Magnesium Alloy Round Bar.

Faster Validation Cycles

Our U.S. entity and weekly project updates keep your timeline moving.

RFQ response in 24 hours. Quotation in 1–3 business days.

No time zone delays. No translation gaps.

Reliable Second Source

Sole sourcing creates program risk.

We help you diversify supply while maintaining quality parity—so you're never stuck waiting on one vendor.

Primary Applications of Round Bar Stock

Dissolvable Frac Plugs & Bridge Plugs

Machine mandrels, slips, and body rings that withstand setting force, hold zone isolation during treatment, then vanish in wellbore brine—no mill-out, no debris.

Dissolvable Balls & Seats

Turn round bar into drop balls and seat inserts for multi-stage shifting.

They seal under pressure, then dissolve to restore full-bore access for production.

Temporary Mandrels & Sleeves

Use as sacrificial structural components in packer assemblies or setting tools.

They deliver mechanical support during deployment and disappear post-job.

Subsea & Geothermal Fasteners

Create temporary bracing or release pins for high-salinity environments where manual retrieval isn't an option.

How to Evaluate Your Supplier?

Chemistry Stability

Ask for melt consistency data across batches.

Alloy composition drift = unpredictable field behavior.

Machinability & Dimensional Tolerance

Request extrusion diameter tolerance and surface roughness specs.

Tight tolerances reduce your machining time and tool wear.

Dissolution Predictability

Demand validated dissolution curves in your target fluid (not just water).

Temperature, salinity, and flow rate all matter.

Traceability & Audit Support

Can they provide material certificates, lab reports, and batch records?

If the answer is "sometimes," keep looking.

Frequently Asked Questions

Q: What is the product mainly used for?

A: It's mainly used for machining dissolvable balls, seats, sleeves, mandrels, and other temporary downhole components. Buyers want to know whether the product can meet target working conditions, machining routes, and final application requirements without creating unnecessary downstream risk.

Q: What key features should buyers evaluate when sourcing this material?

A: Focus on chemistry stability, machinability, dimensional tolerance, and predictable dissolution response. Also assess controlled degradation behavior and strength during the working window. In export purchasing, these factors directly affect processing yield, field reliability, product consistency, and total cost of qualification.

Q: Why do international buyers choose Hagrien?

A: Hagrien combines dissolvable alloy development, extrusion capability, CNC machining support, and batch traceability to help buyers shorten validation cycles and build a reliable second source. This helps customers reduce dependence on a single supplier, improve communication speed, and move from sample validation to stable volume supply more efficiently.

Q: How do you customize the dissolution time?

A: Dissolution is controlled through chemical composition adjustments (micro-alloying) and specific heat treatment processes that alter the electrochemical potential of the alloy.

Q: Can the material withstand high-pressure environments?

A: Yes. Our high-strength grades are designed to withstand differential pressures up to 10,000–15,000 psi in downhole tool configurations.

Q: What happens to the material once it dissolves?

A: The material converts into magnesium hydroxide and hydrogen gas. The magnesium hydroxide forms a fine powder that's easily carried away by wellbore fluids.

Q: What are the storage requirements to prevent premature degradation?

A: Bars must be stored in a temperature-controlled, low-humidity environment—ideally vacuum-sealed or with desiccants to prevent atmospheric moisture from initiating surface oxidation.

Q: Is the dissolution rate linear?

A: While we aim for uniform dissolution, the rate can be influenced by changes in fluid concentration, flow velocity, and temperature, which are factored into our performance modeling.
