Harmonizing Product Transparency and Material Health in the Metal Industry

In a significant stride toward enhancing transparency in material health within the metal sector, the Copper Development Association and WAP Sustainability revealed innovative strategies at the Material Health Symposium IV. Their presentation, titled ‘Allaying Alloy Anxiety: Metal Trade Associations Collaborating to Disclose Material Health Content of Metal Alloys,’ offers insightful exploration into the journey of integrating Health Product Declarations (HPDs) into the realm of metal alloys, underlining the united efforts of trade associations to champion product transparency and material health.

Empowering Trade Associations

The Copper Development Association, serving as the engineering, market development, and information services arm for North America’s copper industry, highlighted its commitment to propelling its members on their product transparency and material health journey. Understanding that collaborations and leveraging industry standards, such as those set by ASTM and ASME, are crucial, the association has pioneered a path for its members to develop Health Product Declarations (HPDs) for metal alloys.

The Unified Numbering System: A Foundation for Transparency

Central to this development is the utilization of the Unified Numbering System (UNS), which catalogs metals and alloys based on their specific chemical compositions. This system, underscored by ASTM International and SAE International, provides a consolidated basis for describing alloys’ unique ‘recipes,’ thus facilitating a clearer understanding of the materials used in products. Through this, an alloy like C12200, widely employed in copper tubes and fittings, can be effectively communicated across various applications underpinned by industry standards.

Streamlining Product Disclosure through Comprehensive Databases

Addressing the need for accessible and comprehensive data, the Copper Development Association and WAP Sustainability embarked on an ambitious endeavor to input over 700 alloys into the 3E Exchange Digital Product Passport Library. A 3E Exchange API supports a seamless transfer of Bill of Material and content inventory information to the HPD Builder, facilitating the creation of both Product and Supplier HPDs. This initiative was backed by meticulously curated databases on sites such as unscopperalloys.org and copper.org, which offer exhaustive chemical composition details, properties, and applicable standards for various alloys.

The Metal Alloy Special Condition

A notable advancement discussed was the creation of the ‘Metal Alloy Special Condition’ in HPDs, designed to illuminate the nuanced hazards associated with metal alloys as opposed to their individual constituents. This distinction aims to provide a more accurate depiction of the risks related to the use of these alloys, enhancing the clarity and usefulness of HPDs.

Simplifying Alloy Reporting in HPDs

The journey includes a pivotal development spearheaded by Alex Co, focusing on the introduction of a best practice guideline for trade associations to publish authoritative Alloy HPDs. This initiative promises to simplify the process for manufacturers in incorporating metal alloy content into their HPDs by linking to or citing these authoritative documents. Such a streamlined approach not only mitigates errors and inconsistencies but also bolsters the accuracy and credibility of material health disclosures.

Future Perspectives

Looking ahead, the goal is to cultivate a unified framework that transcends individual trade associations, enabling a standardized, efficient, and transparent reporting mechanism for metal alloys in HPDs. This collaborative effort underscores an ecosystem that intertwines product HPDs, industry-standard-based HPDs, and robust databases, all aimed at fostering a clearer, more accessible communication of material health information.

In essence, the concerted actions of the Copper Development Association, WAP Sustainability, and their partners signify a monumental shift toward a more transparent, informed, and health-conscious approach in the metal industry’s product disclosures. Through these innovative strategies, trade associations, manufacturers, and stakeholders are equipped to navigate the complexities of material health with greater ease and efficiency, paving the way for a healthier, more sustainable future.
