Nickel titanium alloy, also known as memory alloy, is used in underwear steel rings. Compared with traditional ordinary steel (stainless steel) steel rings, its core is to utilize its two major characteristics of shape memory and super elasticity.

Main function

1. Super elastic, soft and resistant to bending, not easily deformed

Ordinary steel rings will permanently bend and curl when bent too much; Nickel titanium alloy steel rings can be bent and compressed significantly, and automatically rebound back to their original arc shape when released. Washing and twisting, storage and squeezing, body movement squeezing, not easily crooked or deformed, maintaining the support contour of the cup.

2. Memory shaping, fitting chest shape

Having shape memory characteristics, it can stably maintain a preset arc curvature in the human body temperature environment, conform to the contour of the breast base, support the chest, and prevent the steel ring from poking the ribs and running. When worn, it follows the slight deformation of the body and is more suitable for different body shapes than a hard steel ring.

3. Improve wearing comfort and reduce pressure

The hardness is much lower than traditional steel rings, and the flexibility is strong. When turning over, lifting hands, or bending over, the steel ring will slightly deform with the body, reducing problems such as rib cracking, chest compression, and armpit poking, making it suitable for people who are sensitive to hard steel rings.

4. Reduce weight

Under equal support, nickel titanium alloy steel rings are lighter than stainless steel rings, reducing the overall weight of underwear.

Limitations&Precautions

•  Weak support compared to traditional hard steel rings: Soft elasticity, limited upper limit of support for people with large breasts, and it is difficult to achieve strong lifting and gathering of large breasts with it; More suitable for styles with small to medium-sized breasts and a pursuit of comfort.

• The cost is higher, and the nickel titanium steel ring version of the same underwear is generally more expensive.

• Allergy risk: Alloys contain nickel, and a small number of people who are allergic to nickel metal may experience itching and redness at the contact area. It is not recommended for this group of people.

• Although it is resistant to bending, repeated extreme violent pulling and high-temperature ironing can still damage its memory performance.

Summary: Traditional steel rims focus on strong support; The nickel titanium alloy steel ring is characterized by its flexibility, deformation resistance, and comfortable fit, sacrificing some of its rigid support for a better body feel.

Huizhou Pengchengrui Technology Co., Ltd. specializes in the research and production of nickel titanium memory alloy accessories, providing high-quality underwear memory steel rings. Relying on the super elasticity and shape memory characteristics of the alloy, it can be bent freely at low temperatures, automatically recovers upon contact with human body temperature, is flexible and resilient, and is not easily permanently deformed, bidding farewell to discomfort caused by pressure. Lightweight design, fatigue and rust resistance, balancing support and shaping with comfortable wearing, supporting customized specifications, is the preferred core accessory for high-end bras, empowering lingerie brands to upgrade their product experience.
