The phenomenon of microfusion was observed as early as World War I, when bullets were fired into armor plates to join dissimilar metals that were not able to be welded by conventional methods. This also was observed in the remnants of bombed-out bridges in World War II.
It doesn't sound like it would work, but DuPont started welding things together like this on purpose by means of carefully designed explosions and offered its Detaclad process in 1959. The idea was to blast away oxide and all contaminants and join metal by force and molecular intermingling instead of heat and melting. Denver based Martin Marietta licensed this method to build jet engine parts with. In 1965, a group bought Martin's explosion cladding business, and now it is Boulder based BOOM.
It has been a fast grower the last 6 years:
The stock has been in the doghouse all year long except for a brief but severe beating down to near zero in February/March - a measly +7% 52 week return. PE for ttm is a modest 19, price/cash flow is 8.0 - pretty cheap for a stock in a sweet spot of emerging market growth that has grown its cash flow at an annualized clip of a whopping 42% the last 6 years. The recession has dented their results as you'd expect with a deep cyclical. But the stock has been hammered out of proportion to this dip and is now way out of whack with basic cash flow from operations, which is still on a robust growth track. Its technical condition is an extreme quieting pattern:
The 50 and 200 dma have accomplished a positive cross and are now both sloping up, suggesting that the stubborn resistance level at $20 will soon go BOOM.
