2. Что 1050 Алюминиевый лист H22 для номерных знаков?

2.1 Что 1050 Алюминиевый сплав?

1050 алюминиевый сплав относится к 1ххх серия 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

Элемент	Типичный контент	Функция / Влияние
Алюминий	≥99.50%	Provides corrosion resistance, пластичность, легкий вес, и совместимость покрытий
Железо	≤0.40%	Influences strength, grain behavior, and surface appearance
Кремний	≤0,25%	Affects formability and surface consistency
Медь	≤0,05%	Kept low to protect corrosion resistance
Магний	≤0,05%	Контролируемые примеси
Марганец	≤0,05%	Контролируемые примеси
Цинк	≤0,05%	Контролируемые примеси
Титан	≤0,03%	May support grain control
Ванадий	≤0,05%	Controlled trace element

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 (Strain-Hardened and Partially Annealed): 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 (Четверть Hard): The number ‘2’ signifies the degree of final hardness. It represents a “quarter-hard” state, positioning the metal perfectly between fully annealed (O-характер, completely soft) and half-hard (H24).

Этот “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 г/см³, 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, punch, level, and blank.
• Возможность вторичной переработки: aluminum scrap from blanking and punching has recovery value.

5. Процесс производства 1050 Алюминиевый лист H22 для номерных знаков

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.

Поэтому, 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. Во время плавления, the producer controls temperature, дегазация, фильтрация, and impurity levels to reduce inclusions, oxide particles, and internal defects.

5.3 Гомогенизация и горячая прокатка

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. If it is too hard, 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

Before coating, рисование, анодирование, or reflective film bonding, the aluminum surface must be clean and oil-controlled.

Очистка удаляет масло для прокатки., металлическая мелочь, пыль, 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 Резка, Гашение, and Edge Control

The aluminum sheet may be supplied as coil, full sheet, полоска, 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, Рисование, or Reflective Film Preparation

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

Common surface routes include:

Surface Route	Цель
Отделка мельницы	For downstream coating or film lamination
Primer-coated sheet	Improves paint or film adhesion
Painted sheet	Provides background color
Anodized sheet	Improves surface durability and appearance
Reflective film-ready sheet	Supports traffic-grade reflective plate production

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