There a seven levels of indestructibility of adamantium. The different destructibility levels are arrived at by using different isotopes of the metal involved, of which there are seven. Adamantium silver fused to Wolverineís bones is completely indestructible. On the other hand, adamantium orange can be cut with extremely high-powered lasers, and destroyed in powerful nuclear blasts. There is no known way to destroy adamantium silver.
The Canadian government while reviewing the adamantium process used on Wolverine found the results to be too indestructible. The process resulted in a weaponized person who was uncontrollable, but also unconfinable or restrainable. With indestructible claws, there were very few ways of restraining the Wolverine. The government decided to pursue a less durable alloy of adamantium for its own future use; the objective being more easily managed weapons and materials. Indestructible materials are far less useful than destructible ones. The alloy chosen was Adamantium Orange; a metallic orange in colour.
The process used to fuse adamantium orange to the subjectís bones was completely different than that used on Wolverine. Instead of an injection process, the liquid adamantium orange was delivered via pills taken orally. The adamantium orange delivery process was an even more difficult technical feat than the injection process. Made possible with advancements in nano-technologies. Like the silver alloy, the orange alloy must be kept liquid, once itís hardened itís virtually indestructible. The pills are kept in an oven to keep the adamantium orange hot. The pills consist of an exterior hull made from super-insulating foam similar to that used on the space-shuttle. In a year long process, pills are swallowed (with a cooling agent) daily, and the adamantium orange slowly builds up in the bone structure. Part of the process involves creating a digital map of the personís bone structure. Copies of this map are then built into every pill. Pills are based on nano-technologies and have their own rudimentary computer and navigation systems. To aid in the process, a low power radio beacon suit is worn by the subject, while ingesting pills. The pills locate their target area relative to the radio beacons combined with the skeletal map information contained in each pill.
The process remains quite painful, with hot liquid adamantium being applied to bone surfaces; however it is much more manageable than the original adamantium bonding process, as the process is piece-meal year-long.
