It's the copper-based counterpart to the \u003ca href=\"\/products\/fenwicks-lubrication-ptfe-anti-seize-p114731\"\u003eFenwick's PTFE Anti-Seize\u003c\/a\u003e, sharing the same core purpose but using copper particles as the primary anti-galling agent rather than PTFE. Copper anti-seize is a workshop staple with a long track record in both cycling and automotive maintenance, particularly valued for its performance under high temperatures and pressure.\u003c\/p\u003e\n\n\u003cp\u003eThe compound is particularly effective at \u003cstrong\u003etitanium-to-titanium and titanium-to-aluminium interfaces\u003c\/strong\u003e, where galling — the cold-welding of metal surfaces under pressure — is a well-known and costly problem. A thin application to titanium bolt threads before fitting prevents galling entirely. It's equally valuable on steel and aluminium threaded interfaces in high-corrosion areas: bottom bracket threads, pedal threads, seatpost clamp bolts, stem bolts, and any fastener exposed to water and road salt. The packaging allows precise application without a grease gun, making it practical for both workshop and home mechanic use. Like the PTFE version, it can also be applied as a \u003cstrong\u003ethin smear behind disc brake pads\u003c\/strong\u003e to dampen vibration and reduce brake squeal — but must be kept completely away from the rotor and pad friction surface.\u003c\/p\u003e\n\n\u003cp\u003eBrowse the full \u003ca href=\"\/collections\/fenwicks\"\u003eFenwick's range\u003c\/a\u003e or explore our \u003ca href=\"\/collections\/workshop\"\u003eworkshop and maintenance collection\u003c\/a\u003e for complementary products including the \u003ca href=\"\/products\/fenwicks-lubrication-ptfe-anti-seize-p114731\"\u003ePTFE Anti-Seize\u003c\/a\u003e for applications where a PTFE-based compound is preferred.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It's Good For\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePreventing corrosion and seizing on threaded components — bottom brackets, pedal threads, seatpost clamps, stem bolts\u003c\/li\u003e\n\u003cli\u003ePreventing galling at titanium-to-titanium and titanium-to-aluminium interfaces\u003c\/li\u003e\n\u003cli\u003eHigh-temperature and high-pressure applications where copper anti-seize excels\u003c\/li\u003e\n\u003cli\u003eThin application behind disc brake pads to reduce brake squeal\u003c\/li\u003e\n\u003cli\u003ePrecise application without a grease gun — practical for workshop and home use\u003c\/li\u003e\n\u003cli\u003eLong-lasting protection on components that are infrequently removed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It's NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBraking surfaces\u003c\/strong\u003e — never apply to rotors or the friction face of brake pads; this will severely impair braking performance and is a safety hazard\u003c\/li\u003e\n\u003cli\u003eCarbon fibre components — use a dedicated carbon assembly paste instead, which provides grip rather than slip\u003c\/li\u003e\n\u003cli\u003eGeneral-purpose lubrication of moving parts such as chains, cables, or pivot points — use a dedicated lubricant for these\u003c\/li\u003e\n\u003cli\u003eApplications where copper contamination is a concern — the \u003ca href=\"\/products\/fenwicks-lubrication-ptfe-anti-seize-p114731\"\u003ePTFE Anti-Seize\u003c\/a\u003e is the copper-free alternative\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between Copper Anti-Seize and PTFE Anti-Seize?\u003c\/strong\u003e\u003cbr\u003eBoth products protect threaded and interference-fit components from corrosion and galling. The key difference is the anti-galling agent: Copper Anti-Seize uses copper particles, which excel under high temperatures and pressure. The \u003ca href=\"\/products\/fenwicks-lubrication-ptfe-anti-seize-p114731\"\u003ePTFE Anti-Seize\u003c\/a\u003e uses PTFE (polytetrafluoroethylene), which provides a dry lubricating layer and is preferred where copper contamination is a concern. Both are suitable for titanium interfaces and disc brake pad backing plates.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy do titanium components need anti-seize?\u003c\/strong\u003e\u003cbr\u003eTitanium is prone to galling — a form of cold-welding where metal surfaces bond under pressure and friction. This can make titanium bolts effectively impossible to remove without damage. Applying anti-seize to titanium threads before fitting prevents galling entirely and ensures the bolt can always be removed cleanly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I use it behind disc brake pads?\u003c\/strong\u003e\u003cbr\u003eApply a very thin smear to the metal backing plate of the brake pad only — the side that contacts the caliper piston, not the friction material. Keep the compound completely away from the rotor and the pad's friction surface. Even a small amount of contamination on the braking surface will significantly reduce braking performance and require the pads to be replaced.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhich threaded components benefit most from anti-seize?\u003c\/strong\u003e\u003cbr\u003eAny threaded interface exposed to water, road salt, or dissimilar metals benefits from anti-seize. The most common applications on a bike are: bottom bracket threads, pedal threads, seatpost clamp bolts, stem bolts, and any stainless or titanium bolt threaded into an aluminium component.\u003c\/p\u003e","brand":"Fenwick's","offers":[{"title":"Default Title","offer_id":45472134627503,"sku":"FEGCOP8","price":5.2,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/2003\/4223\/files\/1482398539-63928300.jpg?v=1768519827","url":"https:\/\/www.swinnertoncycles.co.uk\/products\/fenwicks-copper-anti-seize-anti-corrosion-compound-for-threaded-titanium-components","provider":"Swinnerton Cycles","version":"1.0","type":"link"}
