[Alloy Selection & Comparison](https://academy.ampcometal.com/migration/en/knowledge/materials-coatings?hsLang=en#alloy-selection-comparison) # What Is AMPCO® 29? ## A Targeted Alternative to AMPCO® 25 for Specific Competitive Situations AMPCO® 29 is an alloy with a similar base to AMPCO® 25 but with a modified chemistry designed to offer improved friction coefficients, wear resistance, and machinability. It was developed as a direct alternative to competitive alloys such as Durit 3+ and Durimet 3+ from Metallindustria, and may be proposed to customers seeking an alternative to those grades. AMPCO® 29 should be positioned carefully and only in situations where a direct alternative to these competitive grades is being sought. It should not be proposed as a general replacement for AMPCO® 25, as cannibalizing the established AMPCO® 25 position is not the intent. Stock in 38.1 mm diameter is available in Woerden for customer trials. - [Fabrication & Processing](https://academy.ampcometal.com/migration/en/knowledge/fabrication-processing?hsLang=en#main-content) - [Forming & Bending](https://academy.ampcometal.com/migration/en/knowledge/fabrication-processing?hsLang=en#forming-bending) - [Welding & Joining](https://academy.ampcometal.com/migration/en/knowledge/fabrication-processing?hsLang=en#welding-joining) - [Cutting & Shearing](https://academy.ampcometal.com/migration/en/knowledge/fabrication-processing?hsLang=en#cutting-shearing) - [Application & Process Guidance](https://academy.ampcometal.com/migration/en/knowledge/application-process-guidance?hsLang=en#main-content) - [Lubrication & Surface Treatment](https://academy.ampcometal.com/migration/en/knowledge/application-process-guidance?hsLang=en#lubrication-surface-treatment) - [Thermoforming & Plastic Processing](https://academy.ampcometal.com/migration/en/knowledge/application-process-guidance?hsLang=en#thermoforming-plastic-processing) - [Oil, Gas & Chemical](https://academy.ampcometal.com/migration/en/knowledge/application-process-guidance?hsLang=en#oil-gas-chemical) - [Temperature & Thermal Limits](https://academy.ampcometal.com/migration/en/knowledge/application-process-guidance?hsLang=en#temperature-thermal-limits) - [Bearings & Wear Components](https://academy.ampcometal.com/migration/en/knowledge/application-process-guidance?hsLang=en#bearings-wear-components) - [Specialty & High-Demand Environments](https://academy.ampcometal.com/migration/en/knowledge/application-process-guidance?hsLang=en#specialty-high-demand-environments) - [Plastic Injection Molding](https://academy.ampcometal.com/migration/en/knowledge/application-process-guidance?hsLang=en#plastic-injection-molding) - [Metal Forming & Deep Drawing](https://academy.ampcometal.com/migration/en/knowledge/application-process-guidance?hsLang=en#metal-forming-deep-drawing) - [Tube Bending & Forming](https://academy.ampcometal.com/migration/en/knowledge/application-process-guidance?hsLang=en#tube-bending-forming) - [Resistance Welding](https://academy.ampcometal.com/migration/en/knowledge/application-process-guidance?hsLang=en#resistance-welding) - [Machining & Tooling](https://academy.ampcometal.com/migration/en/knowledge/machining-tooling?hsLang=en#main-content) - [Cutting Tool Selection](https://academy.ampcometal.com/migration/en/knowledge/machining-tooling?hsLang=en#cutting-tool-selection) - [Grinding & Surface Finishing](https://academy.ampcometal.com/migration/en/knowledge/machining-tooling?hsLang=en#grinding-surface-finishing) - [Materials & Coatings](https://academy.ampcometal.com/migration/en/knowledge/materials-coatings?hsLang=en#main-content) - [Coating Properties & Selection](https://academy.ampcometal.com/migration/en/knowledge/materials-coatings?hsLang=en#coating-properties-selection) - [Tribological Properties](https://academy.ampcometal.com/migration/en/knowledge/materials-coatings?hsLang=en#tribological-properties) - [Thermal Properties](https://academy.ampcometal.com/migration/en/knowledge/materials-coatings?hsLang=en#thermal-properties) - [Standards & Designations](https://academy.ampcometal.com/migration/en/knowledge/materials-coatings?hsLang=en#standards-designations) - [Alloy Selection & Comparison](https://academy.ampcometal.com/migration/en/knowledge/materials-coatings?hsLang=en#alloy-selection-comparison) - [Mechanical Properties](https://academy.ampcometal.com/migration/en/knowledge/materials-coatings?hsLang=en#mechanical-properties) - [Physical & Electrical Properties](https://academy.ampcometal.com/migration/en/knowledge/materials-coatings?hsLang=en#physical-electrical-properties) - [Heat Treatment & Thermal Processing](https://academy.ampcometal.com/migration/en/knowledge/heat-treatment-thermal-processing?hsLang=en#main-content) - [Stress Relieving](https://academy.ampcometal.com/migration/en/knowledge/heat-treatment-thermal-processing?hsLang=en#stress-relieving) - [Grade Conversion & Heat Treatment Upgrades](https://academy.ampcometal.com/migration/en/knowledge/heat-treatment-thermal-processing?hsLang=en#grade-conversion-heat-treatment-upgrades) - [Supply Condition & Post-Delivery Processing](https://academy.ampcometal.com/migration/en/knowledge/heat-treatment-thermal-processing?hsLang=en#supply-condition-post-delivery-processing) [![Chill listening crop-3](https://academy.ampcometal.com/hs-fs/hubfs/AMPCO%20CD%20elements/logo-1.png?width=98&height=25&name=logo-1.png "Chill listening crop-3")](https://academy.ampcometal.com/knowledge?hsLang=en) ampcometal.com Help Center Copyright © 2026, AMPCO METAL S.A.
