The earliest cobalt alloy as biomedical material developed is the CO-Cr-Mo alloy with austenitic structure. The alloy contains approximately 27-30% chromium, 5-7% molybdenum, and small amounts of other elements such as nickel, iron, and carbon. These elements contribute to the alloy's mechanical properties and resistance to wear and tear. Cocrmo Plate,Cocr F75,Astm Cocrmo Plate,Medical Cocrmo Plate TMT INDUSTRY , https://www.tmtmedtech.com
With its excellent mechanical properties and good biocompatibility, especially excellent corrosion resistance, wear resistance and casting properties are widely used. Its corrosion resistance is 10 times stronger than that of Stainless Steel, and its hardness is 1/3 higher than that of stainless steel
Therefore, it is suitable for the production of artificial joints, denture and other medical devices with high abrasion. 50s began to be used in the manufacture of artificial joints.
Cocr F75 as implantable grade casting is commonly used in biomedical applications, particularly in dental and orthopedic implants.
How bicycle theft happens
Over the past year, bicycles have become increasingly valuable, and with that comes a growing problem: bike theft. In cities both big and small, thieves are now well-equipped and organized, making bicycle theft a serious issue. Unfortunately, it’s one of the least solved crimes, leaving many cyclists frustrated and vulnerable.
Understanding where and how theft occurs can help you stay more vigilant and protect your bike from falling into the wrong hands. Here are some common ways bikes are stolen and what you can do to prevent it.
**Left in a Convenient Place**
How is it possible for bikes to be stolen so easily? The answer lies in battery-powered tools. These powerful devices, such as diamond-blade grinders and impact guns, can quickly cut through even the strongest locks. Thieves often target areas where bikes are left unattended, like supermarkets, gyms, train stations, libraries, and more. No place is completely safe—every time you leave your bike, it becomes a potential target.
To reduce the risk, always use high-quality locks. According to a recent comparison by The Best Bike Lock, Abus locks are significantly heavier than other brands, which indicates greater strength. A thief might skip an Abus-locked bike in favor of something easier to steal.
**From a Car**
Many bikes are stolen when they're left on car racks or inside vehicles. Even a short stop at a gas station or grocery store can be enough for a thief to grab your bike. In some cases, thieves work in teams and manage to steal multiple bikes right in front of people without being noticed.
If you plan to leave your bike on a car rack, secure it with a heavy-duty chain. Park your vehicle where it's visible from inside the store or restaurant. This simple step can deter thieves and increase your chances of recovering your bike if it's taken.
**From a Garage**
Garages are one of the most common places where bikes are stolen. Even a closed garage door isn’t a guarantee of safety. Thieves can hack older garage door openers or manually lift the door using an emergency cord. To protect your bike, consider zip-tying the emergency lever or securing your bike to the floor or wall with a strong chain.
If you live in an apartment complex with a shared bike cage, make sure your bike is locked to a solid object inside the cage. Avoid relying on cable locks, and if there are no cameras, consider asking the management to install one.
**From a Balcony**
Bikes stored on balconies, especially on the first or second floor, are easy targets. A ladder or truck can provide access to these areas. If you must store your bike on a balcony, invest in heavy-duty security measures to make it harder for thieves to take.
**From a Backyard**
Even if your bike is hidden in a backyard, it's still at risk. Thieves can find a way in over time. If you keep your bike in a shed, make sure it's locked securely to the structure itself, and never leave it unlocked.
**From the Street**
Commuters are prime targets because their bikes are often left in the same spot for long periods, including after dark. Bikes secured outside during nighttime hours are particularly vulnerable. Always use a heavy chain and lock, and avoid leaving your bike unattended for extended periods.
**Beware of Laws**
Some cities have strict laws against locking bikes to public structures like signposts or parking meters. Violating these rules could result in your bike being removed or left unsecured. Always check local regulations before securing your bike.
**Theft of Parts**
It’s not just the entire bike that gets stolen—thieves often target parts like wheels, seats, lights, and batteries. Use special fasteners that require unique tools to remove, and always lock all parts of your bike, not just the frame.
**GPS and Other Technologies**
Emerging technologies like GPS trackers and motion sensors can help locate a stolen bike. While they offer promise, they often rely on cell service and have limited battery life. Apple AirTags, for example, can be useful in urban areas due to their long battery life and Bluetooth connectivity. However, they require nearby iPhone users to help track the device.
If your bike is recovered, report the theft to the police and provide proof of ownership, such as photos, receipts, and a hidden identifier inside the frame.
**Insurance**
In many areas, bicycle theft isn't a top priority for police. That’s why insurance can be a lifesaver. Velosurance offers policies that reimburse you for the full value of your bike, minus a deductible. Registering your bike with Bike Index can also help law enforcement recover it if it’s stolen.
Protecting your bike starts with awareness and smart security choices. Stay informed, stay prepared, and enjoy your ride with peace of mind.
