What Are Metal Credit Cards Made Of?

Metal credit cards have emerged as a distinctive option in the financial landscape. Unlike traditional plastic cards, these offerings are crafted from various metallic materials, contributing to a different user experience. Their growing popularity stems from a desire for both enhanced durability and a sense of prestige. This physical composition sparks curiosity, prompting many to consider what gives these cards their unique characteristics.

The Core Materials

Metal credit cards are primarily composed of various metals or alloys. Stainless steel is a common choice, valued for durability, corrosion resistance, and a premium feel. Titanium, another frequent material, offers a combination of lightness and exceptional strength, making it a preferred option for some high-end cards. Brass provides a distinct golden hue, lending a luxurious and unique visual appeal to the card.

For cards prioritizing significant heft, tungsten is sometimes utilized. Its high density contributes to a substantial feel and a noticeable sound when dropped. Beyond solid metal constructions, many cards feature a metal core or veneer, where a thin layer of metal is integrated within or on top of plastic materials, often polyvinyl chloride (PVC). This hybrid approach allows for a metallic feel while potentially managing production costs and card functionality.

Beyond the Metal: Card Construction

The manufacturing of metal credit cards involves intricate processes to transform raw materials into functional payment instruments. Metal sheets are precisely cut and shaped, and card details such as the cardholder’s name and account number are applied through laser etching or engraving. These techniques create a permanent, tactile finish on the metal surface, enhancing both aesthetics and security. Additional finishing steps, including polishing or coating, further protect the card from scratches and corrosion.

Integrating essential components into a metal structure presents specific engineering challenges. The EMV chip, which provides advanced security features, is carefully embedded into the card. Magnetic stripes are affixed to the card’s reverse side, storing transactional data. For contactless payment functionality, a thin antenna is integrated around the chip and laminated within the card’s layers, sometimes requiring non-conductive inserts or slits in the metal to ensure proper signal transmission.

The Distinctive Feel and Durability

The material composition of metal credit cards imparts several distinctive physical characteristics that set them apart from their plastic counterparts. Users immediately notice the increased weight, which contributes to a perception of quality and substance. When placed on a hard surface, metal cards often produce a unique “clink” or “thud.” The tactile sensation of holding a metal card is also different, often described as cool, smooth, and substantial.

This choice of metallic materials also significantly enhances the card’s durability. Metal cards exhibit superior resistance to bending, cracking, and general wear and tear that commonly affect plastic cards over time. Their robust construction means they are less prone to scratches and can maintain their aesthetic appeal for a longer duration. This increased resilience contributes to a longer lifespan for the card.
