2. Что 1050 H22 Aluminum Sheet for License Plates?

2.1 Что 1050 Алюминиевый сплав?

1050 алюминиевый сплав принадлежит 1серия xxx из алюминия, known for its Высокая чистота (минимум 99.5% алюминий) и отличная коррозионная стойкость.

It is a non-heat-treatable alloy that offers outstanding formability and is widely used in applications requiring superior surface finish and moderate strength.

2.2 Химический состав 1050 Алюминиевый сплав

The high aluminum content gives 1050 its key advantage: clean formability and strong outdoor corrosion resistance.

2.3 What Does H22 Temper Mean?

The temper designation is the most critical factor for license plate manufacturing. "H22" represents a specific thermomechanical history:

• H2 (Деформационно-упрочненная и частично отожженная): The metal is cold-rolled to increase its strength (деформационное упрочнение) and is then passed through a thermal furnace to partially soften it back to a specific mechanical state.
• 2 (Quarter-Hard): The number '2' signifies the degree of final hardness. It represents a "quarter-hard" Таким образом, штампы для штамповки следует регулярно проверять на допуск и обрезку., positioning the metal perfectly between fully annealed (O-Temper, completely soft) and half-hard (H24).

и у каждого есть свои замечательные свойства материала "quarter-hard sweet spot" means the metal retains enough yield strength to remain flat and rigid on a vehicle bumper, but is ductile enough to endure the deep, localized stretching required to emboss 3D letters and numbers without tearing or "orange-peeling" at the edges.

2.4 Why License Plates Use 1050 Алюминий

License plate manufacturers choose 1050 aluminum because it matches the actual working conditions of vehicle plates.

Main advantages include:

• Легкий вес: aluminum density is about 2.70 Алюминиевая алмазная пластина представляет собой разновидность алюминиевой пластины., much lower than steel.
• No red rust: aluminum forms a natural oxide layer that helps resist corrosion.
• Good embossing formability: raised letters and numbers can be stamped cleanly.
• Surface compatibility: suitable for paint, покрытие, анодирование, and reflective film.
• Mass-production efficiency: easy to shear, Это может уменьшить вес корабля, уровень, and blank.
• Возможность вторичной переработки: aluminum scrap from blanking and punching has recovery value.

3. Технические характеристики 1050 H22 Aluminum Sheet for License Plates

Common license plate sheets often fall around 0.6-1.2 мм толщина, depending on country, plate type, embossing depth, and rigidity requirements.

Final thickness should follow the applicable local vehicle registration plate standard.

4. Механические и физические свойства

Because mechanical properties vary by thickness and production route, buyers should rely on the supplier’s mill test certificate for final values.

5. Процесс производства 1050 H22 Aluminum Sheet for License Plates

Процесс изготовления 1050 H22 aluminum sheet for license plates must control both the aluminum substrate and the final surface condition.

License plate production requires clean surfaces, stable flatness, accurate thickness, and reliable embossing performance.

Следовательно, each production stage affects the final plate’s appearance, долговечность, and processing efficiency.

5.1 Raw Material Selection and Alloy Control

Production starts with high-purity aluminum raw material.

С 1050 алюминий содержит ≥99.50% aluminum, the mill must control impurity elements such as iron, кремний, медь, магний, марганец, и цинк.

For license plates, chemical consistency matters because different batches must behave similarly during blanking, штамповка, покрытие, and reflective film lamination.

5.2 Плавка и литье

The selected aluminum is melted and cast into slabs or coils. During melting, the producer controls temperature, дегазация, фильтрация, and impurity levels to reduce inclusions, oxide particles, and internal defects.

5.3 Homogenization and Hot Rolling

После кастинга, homogenization improves the internal structure of the aluminum and reduces segregation.

Hot rolling then reduces the material thickness and prepares it for cold rolling.

Good hot rolling control helps produce a more uniform sheet, which later improves flatness and embossing consistency.

5.4 Cold Rolling to Target Gauge

Cold rolling further reduces the sheet to the required thickness.

For license plate materials, common thickness ranges may be around 0.6-1.2 мм, depending on local standards, plate type, and embossing depth.

Cold rolling improves dimensional accuracy and surface smoothness. It also increases strength through strain hardening, which is necessary before final H22 temper control.

5.5 H22 Temper Control

The H22 temper is achieved through strain hardening and partial annealing.

This step gives the material a quarter-hard condition, balancing strength and formability.

If the temper is too soft, the finished plate may bend too easily. Если это слишком сложно, the embossed areas may crack or show surface damage.

5.6 Tension Leveling and Flatness Correction

Flatness is critical for license plates, especially when the sheet will receive printing, покрытие, or reflective film.

Tension leveling reduces waves, internal stress, and shape defects.

Poor flatness can cause film bubbles, printing misalignment, uneven embossing, or plate warping.

5.7 Surface Cleaning and Pretreatment

Перед нанесением покрытия, картина, анодирование, or reflective film bonding, the aluminum surface must be clean and oil-controlled.

Cleaning removes rolling oil, metal fines, пыли, Отпечатки пальцев, and oxidation residues.

This stage directly affects coating adhesion and reflective film bonding.

If oil or dust remains on the surface, the plate may suffer from coating peeling, film delamination, пятна, or poor weather resistance.

5.8 Ингредиенты-резка-канавка-резка углов-гибка-доска-сборка-армирование-повторная проверка, Гашение, and Edge Control

The aluminum sheet may be supplied as coil, full sheet, Композитный метод формирования, or cut-to-size blanks.

License plate manufacturers often require precise dimensions to match plate standards and stamping dies.

Low-burr edges improve safety and reduce problems during coating, ламинирование, и установка.

5.9 Покрытие, аналогичная форма и тот же процесс, or Reflective Film Preparation

Depending on the final license plate system, the sheet may be prepared for different surface processes.

Common surface routes include:

For reflective license plates, чистота поверхности, плоскостность, and adhesion performance are especially important because the film must remain bonded under UV exposure, дождь, высокая температура, cold, and washing chemicals.
