At TCT Asia 2026, AVIMETAL launched the MT-DV06 Hot Work Die Steel Powder—a comprehensive additive manufacturing solution designed specifically for the demanding requirements of die-casting, hot forging, and extrusion applications. Beyond the powder itself, AVIMETAL delivers a full-process AM solution that systematically addresses the challenges of producing high-performance hot work tooling.
Molds used in high-temperature metal forming processes must withstand extreme thermal cycling, mechanical stress, and wear. Traditional materials like H13 have served the industry for decades, but the MT-DV06 raises the bar with superior high-temperature strength, thermal fatigue resistance, and dimensional stability—all while enabling the design freedom of additive manufacturing.
The MT-DV06 is engineered from composition to heat treatment, ensuring that every step of the additive manufacturing workflow is optimized for reliability and performance.
MT-DV06 delivers excellent strength and thermal fatigue resistance, maintaining hardness even at elevated operating temperatures. This makes it ideal for molds that undergo repeated thermal cycling, reducing the risk of heat checking and premature failure.
After heat treatment, the material offers a hardness range of 40–52 HRC, providing flexibility to balance wear resistance and toughness. Manufacturers can tailor the final properties to match specific application requirements, whether prioritizing durability against abrasive wear or resilience against impact.
One of the critical challenges in tooling applications is maintaining accuracy through heat treatment. MT-DV06 exhibits superior dimensional stability, ensuring that complex mold geometries retain their precision after post-processing. This is essential for meeting the tight tolerances required in modern die-casting and forging operations.
AVIMETAL’s approach goes beyond powder formulation. The MT-DV06 solution includes full-chain optimization—from composition design to step heat treatment—systematically addressing common issues such as cracking, distortion, and inconsistent properties. This holistic methodology ensures that users can achieve reliable, repeatable results with confidence.
Parts produced with MT-DV06 achieve a density of 99.9%, meeting the stringent requirements of high-pressure die-casting and hot forging environments. High density translates to better mechanical properties, reduced porosity, and improved mold life.
When compared to conventional H13 hot work tool steel powder, MT-DV06 offers distinct performance advantages:
| Attribute | Traditional H13 | MT-DV06 |
|---|---|---|
| High-Temperature Strength | Standard | Higher |
| Thermal Fatigue Resistance | Moderate | Better |
| Dimensional Stability after Heat Treatment | Variable | Superior |
These improvements make MT-DV06 a compelling choice for applications where mold longevity and part quality are critical.
MT-DV06 is specifically formulated for tooling applications that demand exceptional performance under extreme conditions:
Die-Casting Molds – For aluminum, magnesium, and zinc die casting, where thermal cycling and erosion resistance are paramount.
Hot Forging Dies – Withstands repeated impact and high temperatures in forging operations.
Extrusion Dies – Maintains dimensional accuracy and wear resistance during continuous extrusion processes.
Automotive Parts Casting – Enables complex cooling channels and optimized mold designs for high-volume automotive production.
Precision Forging and Aerospace Components – Supports the production of critical components requiring consistent material properties and tight tolerances.
The MT-DV06 powder has been validated across AVIMETAL’s broad LPBF platform, ensuring seamless adoption for both existing users and new installations. Compatible systems include:
MT170H
MT280
MT400M
MT450

This wide compatibility allows manufacturers to standardize on a single high-performance material across multiple machine sizes and configurations.
The introduction of MT-DV06 Hot Work Die Steel Powder, combined with AVIMETAL’s full-process AM solution, represents a significant step forward in additive manufacturing for tooling applications. By delivering superior high-temperature performance, adjustable hardness, and outstanding dimensional stability, MT-DV06 enables mold makers and foundries to produce more durable, reliable tooling with complex geometries that were previously difficult or impossible to achieve.
For industries ranging from automotive to aerospace, this solution offers a pathway to improved mold life, reduced cycle times, and ultimately, lower total cost of ownership.
