ENGINEERED RESPONSE PRODUCT DESCRIPTION: DISSOLVABLE ALLOY TervAlloy™ 3143 (HD) is a special high ductility version of Terves’ patented dissolvable magnesium designed for oil and gas applications. This material is based on our TervAlloy™ 3241 (TAx100E) product offering, and demonstrates similar dissolution rates in potassium chloride and sodium chloride brine solutions. This product can be purchased in one inch increments in lengths up to 48 inches (depending on shape). TervAlloy™ tubular TervAlloy 3143 is designed for higher ductility applications – allowing greater flexibility to meet the needs of specific customer applications.
