Spur products Meet Your Needs For A Dissimilar Metal Interface. Current Applications Include:

Aluminum Smelting Industry

Spur DMI Inserts are designed and manufactured to perform in real world operating conditions.

The connections between aluminum buss systems and the steel anodes and cathodes used in aluminum and magnesium reduction cells are system critical contact points. Spur DMI Transition Inserts provide the robustness and reliability you need for these critical components. Our transition inserts utilize a proprietary alloy and bonding process to achieve a 550⁰ C temperature rating that also facilitates field welding and minimizes weld cracking which will reduce your plant maintenance costs over the long run.

Marine Industry

Spur DMI, GII, ECI and WRI products will solve your toughest material connection problems.

Joining dissimilar metals is a necessary element of modern shipbuilding. In a salt water environment, concerns about galvanic corrosion, weight, and electrical conductivity play important roles in the design process. Spur addresses these concerns with our DMI, GII, ECI and WRI product lines.

  • Our galvanic inhibitor interface allows the connection of like metal to like metal with a
    clad metal interface that substantially eliminates system degradation caused by galvanic
    corrosion.
  • Our electrical conductor interface prevents oxidation and the associated reduction in
    conductivity when transitioning from one electrical conductor to another of a dissimilar
    metal.
  • Spur weight reduction interface products allow lightweight aluminum components to be
    permanently fastened to stronger structural steel components without the attendant
    concerns of corrosion at the dissimilar metals interface.

Plumbing Industry

Spur GCI Couplers provide a connection that will last.

Plumbing systems require robust connectors able to withstand pressure without ever leaking. When those systems involve connection points between dissimilar metals, galvanic corrosion is a significant concern. Spur GCI Couplers address the galvanic corrosion problem. Spur roll clads the dissimilar metals in a proprietary process that produces a metallurgically bonded interface. This allows the installer to connect like metal to like metal with welded, braised, threaded, and/ or compression fittings. The interface between the two metals is permanent and substantially eliminates galvanic corrosion without the need for a gasketed dielectric coupler providing a cost effective solution to a common problem. Spur’s GCI Couplers are rated to 450⁰ C. The pressure rating of the bonded connection will equal or exceed the rating of the pipes being connected.

Power Generation and Distribution

Stay connected with Spur ECI Connectors.

Cost, weight, and other considerations may mandate that electrical power generation and distribution systems utilize connection points between dissimilar metals. Spur ECI Connectors provide a cost effective solution to the problem of oxidation and degradation of conductivity when dissimilar conductors are directly and mechanically connected. The dissimilar metal interface on our roll bonded ECI Connectors simply does not oxidize or degrade. Your connection points will be like metal to like metal and our interface will continue to perform for the long term.

Trailer Manufacturing and Transportation Industries

Spur DMI, GII, ECI and WRI products will solve your toughest material connection problems.

The need to join dissimilar metals is a common occurrence in manufacturing transportation equipment. High fuel prices are driving the push for lighter transportation equipment. Harsh road chemicals and wet environments create concerns about galvanic corrosion. Frame bodies may need to be electrically electrically conductive to maintain the integrity of the vehicle’s electrical
systems. Spur addresses these concerns with our DMI, GII, ECI and WRI product lines.

  • Spur weight reduction interface products allow lightweight aluminum components to be
    permanently fastened to stronger structural steel components without the attendant
    concerns of corrosion at the dissimilar metals interface.
  • Our galvanic inhibitor interface allows the connection of like metal to like metal with a
    clad metal interface that substantially eliminates system degradation caused by galvanic
    corrosion.
  • Our electrical conductor interface prevents oxidation and the associated reduction in
    conductivity when transitioning from one electrical conductor to another of a dissimilar
    metal.
