THE ART OF THE STEEL
If you want to know why today's fairway woods and hybrids produce longer shots, brush up on your science. Specifically, metallurgy. Many new designs use exotic steel alloys in the face to improve ball speed. Their names (455, 475, HT1770, C300) and geeky ingredients (molybdenum, anyone?) might sound dull, but their properties are white hot. These metals have what's called "high tensile strength," which means they can endure a lot of stress (sometimes 250,000-plus pounds per square inch) before failure. The greater the strength, the thinner companies can make a clubface, which means more flex and less weight. (That saved weight can be used to preserve stability on off-center hits, control spin and enhance energy transfer.) Those are good reasons to like these metals, but here's a better one: Some are used in missile casings and jet fighters. Here are 10 new metalwoods to help you launch a few of your own ▶
