J-B Weld is one of the best adhesives I have ever come across. J-B Weld will adhere to iron, steel, aluminum, brass, bronze, copper, pewter, wood, porcelain, ceramic, plastic, and more.

Instructions for use: Mix equal amounts of both tubes together on a disposable surface. Apply desired amount of the mixture to the cleaned surface of the object with a putty knife, spoon, wooden paddle, or other suitable tool. Wait 4 to 6 hours before handling, however it needs to sit for about 15 hours before use. J-B Weld’s maximum temperature is 600 degrees Fahrenheit and its tensile strength is 3960 PSI.

Examples of use: A parts store in Waco, Texas repaired a 20-ton hydraulic jack with J-B Weld and saved $99.00. The city of Dallas, Texas repaired a cracked Caterpillar engine block with J-B Weld and saved $4,000.00 plus 30 days down time. A lady from Seattle repaired her cracked kitchen disposal with J-B Weld. Lastly in Bangor, Maine a computer gamer repaired his discontinued Sidewinder Dual Strike game pad in time to dominate Unreal Tournament in a recent LAN party.

J-B Weld can be purchased at most home improvement stores for about $4.

J-B Weld is a two-part epoxy-type adhesive known for its high tensile strength, especially when used on metal parts. 

There are many examples where farmers repaired cracked engine blocks on tractors using J-B Weld. In fact, if you're curious about how good this repair compound is, go on YouTube and search for "jb weld" and "project farm". He has several videos on the product, but the one I would recommend would be the one where he uses it on a cylinder head of a lawn mower. Project Farm is well known as a small engine and mower one-man destructive force. To test J-B Weld, he cut holes in an aluminum cylinder head of an old lawn mower after he had calculated the cylinder pressure. After angle grinding the cylinder head, he repaired it using J-B Weld and let it sit long enough to cure. Then he proceeded to mow a lawn with the now-repaired mower.

With that said, J-B Weld is really supposed to be a temporary fix, at least on paper. If your repaired object has high pressure and temperatures, it may flake off in pieces due to the different thermal expansion properties of the repair and the object itself. Farmers, being practical, will wait until the J-B Weld finally starts to degrade on their engine block repairs and call out the local welder to make a more permanent fix. Sometimes that takes years to happen.

Since J-B Weld is so inexpensive and readily available at home repair stores and Walmart in the United States, it's a good thing to keep in your kitchen junk drawer for the time you may need it. I've used it on copper pipes after punching a hole when hanging heavy paintings. Worked like a charm and never leaked.
